Generator Installation & Maintenance Vancouver
Metro Vancouver gets hit with outages every windstorm season. Whether you need a transfer switch for a portable generator or a permanently installed standby system, Kato Electrical installs and maintains generators across Vancouver — licensed, permitted, and done right. Residential and commercial. Free assessments, no obligation.
Why Vancouver Homes and Businesses Need Generators
Metro Vancouver loses power regularly — particularly from October through March when windstorms hit the Lower Mainland, North Shore, and Fraser Valley. BC Hydro outages affect thousands of homes at a time, and the pattern is consistent enough that "I need a generator" is one of the most predictable realisations a Vancouver homeowner has. The issue is that most people have that realisation the morning after a 10-hour outage, not before. And by then, generator installers are booked out for weeks.
Windstorm Season Is Reliable
The Lower Mainland's autumn and winter wind events are not anomalies — they are a regular feature of living here. The Burrard Inlet corridor, North Shore, and Fraser Valley are particularly prone to extended outages when major systems come through. If you've lived in Metro Vancouver for more than a few years, you've already experienced this firsthand.
Medical Equipment Dependencies
CPAP machines, refrigerated medications, powered mobility equipment, and home oxygen systems don't stop being necessary because the grid is down. For a significant number of Vancouver households, an outage is not an inconvenience — it's a medical situation. A transfer switch and generator changes that equation entirely.
Sump Pumps Fail Exactly When You Need Them
Vancouver's wet climate means losing power during a storm often means losing your sump pump at the worst possible moment. Basement flooding risk spikes precisely during the conditions that knock out the grid. A generator circuit prioritising the sump pump is one of the most practical investments a Lower Mainland homeowner can make.
Commercial Vulnerability Is Measured in Real Dollars
Restaurants lose inventory. Medical clinics lose appointment revenue and potentially compromise cold-chain storage. Data storage operations go offline. Cold chain logistics stop. For commercial properties in Vancouver, a generator is not a luxury — it's the difference between a temporary inconvenience and a significant financial event.
We get more generator calls in November and December than any other time of year — the day after a windstorm that knocked out power for 10,000 homes. The best time to install a generator is before that call becomes urgent. After a major outage, installation lead times stretch considerably.
Transfer Switch Installation — Why It's Not Optional
This is the most important safety and legal point on this page, so it's stated clearly and early: connecting a generator to your home without a transfer switch is illegal in BC. Full stop. It also creates a danger that most people haven't thought through — and it's serious enough that we explain it every time we get this call.
What a Transfer Switch Does
A transfer switch disconnects your home from BC Hydro's grid before the generator powers your circuits. Without that disconnection, your generator's power flows back through the meter and into the utility lines — energising what lineworkers believe are dead wires while they're trying to restore power after an outage.
Connecting a generator directly to your panel without a transfer switch is illegal under BC Electrical Code and can kill BC Hydro lineworkers working on lines they believe are dead. This is called backfeed — and it is one of the most preventable causes of electrical worker fatalities.
Kato installs transfer switches properly — every time, with a permit. If your generator is currently connected without one, call us: (604) 239-3084
Types of Transfer Switches — What Kato Installs
Interlock Kit
A mechanical lock installed in your panel that prevents the main breaker and generator breaker from being on simultaneously. Most affordable option. Requires manual operation but provides full code-compliant isolation.
Manual Transfer Switch
A separate sub-panel with pre-selected circuits that switch to generator power manually. More organised than an interlock kit — you choose which circuits are generator-powered during installation, not during an outage.
Automatic Transfer Switch (ATS)
Detects a grid outage and switches your home to generator power automatically — no manual action required. Required for standby generators. Also available for portable generator setups where zero-intervention matters (medical equipment, vacation properties).
Transfer switch installation requires a permit from Technical Safety BC in BC — no exceptions. Kato handles this as part of every installation. We've also been called to correct improper generator connections regularly: the extension cord through the window, the direct panel tap without isolation. The fix is always more expensive than doing it right the first time.

Generator Installation Cost in Vancouver
We don't publish fixed prices because generator installation cost varies significantly depending on your specific situation. What we do provide is free, detailed assessments — you'll know exactly what's involved before committing to anything.
Here are the factors that determine the cost of your installation:
Generator Type and Size
Transfer switch for a portable generator is the most affordable option. Standby generator installations involve the generator unit itself plus installation. Whole-home systems are the highest investment.
Transfer Switch Type
Interlock kits are the most affordable. Manual transfer switch sub-panels are mid-range. Automatic transfer switches (required for standby units) are the premium option.
Panel Condition and Capacity
If the existing panel needs upgrading before a generator system can be added, that's part of the project scope. Older 100-amp panels in pre-1980 Vancouver homes often need assessment. Panel upgrade service →
Fuel Source and Connection
Natural gas standby units require gas line connection work coordinated with a gas contractor. Propane installations involve tank placement and propane line installation. Portable generators use on-site fuel — no connection required.
Installation Location and Access
Generator pad preparation, outdoor enclosure requirements, distance from the panel, and access for installation all affect the scope and cost.
Permits and Inspection Fees
Technical Safety BC permit fees for generator and transfer switch installation are included in every Kato quote. BC Hydro coordination fees for standby installations are also factored in.
The cost of not having a properly installed generator is worth understanding: food spoilage, lost refrigerated medications, basement flooding from a failed sump pump, and for commercial properties, revenue loss and potential health code issues from cold chain failure. We provide free assessments — the only cost is not knowing what your property actually needs.
Generator Installation and BC Electrical Code — What Requires a Licensed Electrician
All transfer switch and generator electrical connection work in BC requires a licensed electrician and a permit from Technical Safety BC. No exceptions. This applies to portable generator transfer switches, standby generator installations, and any generator-related wiring work. The permit triggers a Technical Safety BC inspection after installation.
What happens when generator work is done without a permit: your home insurer can deny a claim arising from the unpermitted installation, the liability for any incident shifts entirely to you, and when your home goes to market a buyer's inspector will flag the unpermitted work. Fixing it after the fact — permitting and inspecting work that's already installed — is more expensive and complicated than doing it right initially.
If you've had generator work done without a permit and you're not sure where that leaves you, call us. We inspect and correct improper generator installations regularly in Vancouver, and we'll tell you honestly what it involves to bring it up to code. We don't make it awkward — we've seen enough of these situations to treat them as a practical problem to solve, not a judgment to make.
For the full BC context on permit requirements and what homeowners can do themselves, our DIY electrical wiring guide covers the rules clearly. The short version: generator electrical work is not homeowner-permittable in BC.

Types of Generator Solutions Kato Installs
The right solution depends on your property, your load requirements, how much you're willing to spend, and how much intervention you want to perform during an outage. Here's what we install — and when each makes sense in a Vancouver context.
Portable Generator Transfer Switch Setup
The most common residential generator installation we do in Metro Vancouver. The homeowner already has or purchases a portable generator — Kato installs the transfer switch and wires the dedicated generator circuits into the panel. The result is a code-compliant, safe connection point for the portable generator, with the selected circuits isolated from the BC Hydro grid when the generator is in use.
We help homeowners select which circuits to prioritise — the choice matters. Standard priorities for a Vancouver home: furnace or heat pump, refrigerator, sump pump, a few lighting circuits, and any medical equipment circuits. This covers life safety and basic comfort without requiring a generator large enough to run the whole house.
Transfer switch options range from an interlock kit to a manual sub-panel to an automatic transfer switch — we'll recommend the right one for your situation and budget during the assessment. Book a transfer switch assessment →
Standby Generator Installation
A permanently installed standby generator connects directly to your home's electrical system through an automatic transfer switch. When BC Hydro goes down, the system detects the outage and starts the generator automatically — typically within 10 to 30 seconds — without anyone touching anything. When grid power returns, it transfers back and shuts the generator down.
Fuel options in Vancouver's context: natural gas is the most common choice for Lower Mainland installations — it connects to the existing utility supply, which means no fuel storage and no running out during an extended outage. Propane is the right answer for properties without natural gas service, particularly on the North Shore and in rural areas.
Sizing is based on a load calculation — what you want covered determines the generator size required. Partial load (essential circuits only) is meaningfully more affordable than whole-home coverage and covers most homeowners' actual needs. Panel capacity is assessed as part of every standby installation →
Whole-Home Generator Systems
A whole-home generator system powers every circuit in the home when the grid goes down — no prioritisation, no load shedding, no compromise. This is the most capable and most expensive residential option. It requires a full load calculation, panel assessment, and generator sizing that accounts for the peak simultaneous load of all circuits that could run at once.
When whole-home is worth it: properties with medical equipment that can't tolerate interruption, vacation properties where the owner may be remote when an outage occurs, homes with significant electric heating or cooling systems that need to maintain temperature, and homeowners who simply want zero compromise during an outage. Call for a whole-home assessment →
Commercial Generator Installation
Commercial generator installations involve larger load requirements, stricter compliance standards, fuel storage considerations, and in most cases mandatory maintenance agreements. What stays on when the grid goes down is a critical load analysis, not a general preference — it's informed by life safety, regulatory requirements, business continuity, and equipment protection priorities.
Vancouver industries Kato serves: hospitality and food service (cold chain, kitchen equipment), medical clinics and dental practices, technology companies with server infrastructure, property management (elevator power, common area lighting, security systems), and light industrial facilities. Every commercial installation involves Technical Safety BC compliance and Vancouver Fire Department notification where applicable.
What Does Generator Installation Actually Involve?
We've installed generators across Metro Vancouver — from transfer switches in North Shore homes that lose power every November to standby systems in commercial properties where downtime costs real money. The process is the same: assess properly, recommend honestly, install with a permit.
-
1
Assessment Site visit, load calculation, existing panel assessment, location suitability for the generator unit, fuel source confirmation (natural gas connection availability or propane storage), and a noise bylaw check for your Vancouver municipality. We don't recommend anything before we've seen the property.
-
2
Recommendation and Quote Generator type, size, transfer switch type, and circuit prioritisation — based on the actual assessment. The quote is detailed: equipment, wiring, transfer switch, permit fees, and any panel work required. No surprises. Panel assessment included where needed →
-
3
Permits and Coordination All generator and transfer switch installation in BC requires a permit from Technical Safety BC. For standby generators connecting to natural gas, we also coordinate the required notification with BC Hydro. Kato handles the permit process — it's included in every quote.
-
4
Installation Transfer switch installation, generator pad or placement, fuel line connection (coordinated with the gas contractor for natural gas units), electrical connection, circuit wiring, and physical mounting and weatherproofing of all outdoor components.
-
5
Testing and Handover Load testing under power, transfer switch operation testing, automatic start test for standby units, homeowner walkthrough on operation and maintenance basics, and complete documentation — permit, inspection sign-off, and system specifications — for insurance and future maintenance reference.
Timeline: a portable generator transfer switch installation is typically a half-day to full-day job. A standby generator installation involves additional coordination — BC Hydro notification and gas line connection add time — and is typically completed over one to two days once all components are on-site.
↑ Back to topGenerator Maintenance — Why It Matters More Than Most People Realise
The most neglected aspect of generator ownership. A generator that hasn't been tested or serviced regularly is not backup power — it's a liability with a pull cord.
The generator that hasn't run since the last big storm has a lot of opinions about whether it will start during the next one.
What happens to unserviced generators: stale fuel varnishes the carburettor and fuel lines, the battery discharges and sulfates, transfer switch contacts corrode, engine components seize from inactivity. Vancouver's damp climate accelerates certain failure modes — corrosion and moisture ingress affect outdoor installations particularly. A generator in this condition doesn't start reliably when you need it. It starts sometimes, if you're fortunate and persistent.
What Kato Generator Maintenance Includes
Load Testing Under Power
Running the generator under actual electrical load confirms it's producing correct voltage and frequency and that the transfer switch operates correctly. This is the only reliable test — a generator that starts under no load but fails under load is not maintained.
Transfer Switch Operation Test
Confirming the transfer switch isolates correctly, transfers cleanly, and returns to grid power without incident. Transfer switch contacts can degrade without the failure being obvious until you need it.
Battery Inspection and Replacement
Electric-start generators depend on a battery. Testing and replacing batteries before they fail prevents the most common standby generator startup failure in Vancouver's climate.
Oil, Filter, and Fuel System Service
Oil and filter changes per manufacturer schedule, fuel stabiliser verification for stored fuel, and carburettor inspection for units that run infrequently. Stale fuel is the number one cause of generator failure at the worst possible moment.
Coolant and Corrosion Inspection
Coolant check for liquid-cooled units, visual inspection of all electrical connections for corrosion, and physical inspection of the enclosure and weatherproofing for outdoor installations in Vancouver's wet climate.
Annual service minimum for residential standby generators. Quarterly for commercial applications and medical-dependency situations. Self-test monthly run cycles (available on most standby units) supplement but do not replace professional servicing.
