Generator Maintenance and CSA C282 Inspections

GenWorx maintains standby generators across Ontario on the CSA C282 schedule: weekly, monthly, twice a year and once a year. Every visit is written in your log book, on any make.

What the rules ask

What CSA C282 asks of a building owner

Ontario’s Building Code says emergency generators must be installed and maintained to CSA C282, the standard for emergency power in buildings. The building owner is responsible for meeting it. We do the work, on any make, and keep your records ready for an inspector.

The Electrical Safety Authority explains what that means in ESA Bulletin 2-22-3:

  • The owner, or someone acting for the owner, is responsible for meeting C282.
  • A full load test is needed every year.
  • A permanent log book of the work must be kept and shown to ESA when asked.
  • The people doing the work must be trained for it.

Routine inspection and testing, including a load bank test, does not need an ESA notification as long as the log book is kept. Repairs, and replacing wiring or devices, do. For more detail, read our guide to CSA C282 in Ontario.

The CSA C282 schedule

Standby generator maintenance, visit by visit

01

Weekly inspections

A visual check of the generator and its systems: controller in Auto with no alarms, fuel, oil and coolant levels, battery and charger, block heater, leaks and air flow. Written in the log book every week.

02

Monthly inspections

The weekly checks, plus a test run of the generator under load. We write down the voltage, frequency, temperatures and pressures.

03

Semi-annual service

A closer inspection and service of the engine, cooling, fuel, starting and control systems. Any wear we find is reported and priced before it is fixed.

04

Annual service and load test

A full service and a full load test with a load bank, while the building stays on utility power. You get a written report you can give to an inspector or an insurer.

How it works

A full maintenance plan, or one that fills the gaps

Some buildings want us to handle everything. Others have their own maintenance staff who already do the weekly checks. We do not sell you work you already do.

If your team does the weekly round, we build a plan for the monthly, semi-annual and annual work, plus anything your staff are not able to do. The whole schedule ends up in one log book. Load testing, thermal imaging, fluid analysis and fuel polishing can be added to any visit.

All makes, one provider: Cat, Cummins, Kohler, Generac, MTU and many others, plus the automatic transfer switches that go with them, including ASCO, Thomson, Cutler-Hammer and Zenith. If you manage several buildings with different generator brands, one plan, one schedule and one point of contact can cover them all.

Common questions

Generator maintenance questions

How often does a standby generator need maintenance?

Under CSA C282, emergency generators are inspected every week and every month, serviced twice a year, and given a full service and a full load test once a year. Your plan sets which of those visits we do and which your own staff do.

Is CSA C282 maintenance required in Ontario?

Yes, for emergency generators required by the Building Code, and the building owner is responsible for it. Many owners of other standby generators follow the same schedule because it keeps the generator reliable.

Can you take over a generator another company has been maintaining?

Yes. Most of the generators we look after were installed or serviced by someone else before. We start with an inspection, review the log book and tell you what is due.

Do you work on every brand?

Yes. We service Cat, Cummins, Kohler, Generac, MTU and most other makes, plus the transfer switches that go with them.

What happens if a visit finds a problem?

You hear about it the same day, in plain words, with a written quote to fix it. We do not start repairs you have not approved.

Where do you offer generator maintenance?

We are based in Ajax and maintain generators across the Greater Toronto and Hamilton Area: Ajax, Pickering, Whitby, Oshawa and the rest of Durham Region, Toronto, York, Peel and Halton Regions, and Hamilton. Buildings spread across several Ontario sites can go on one plan.
