Power outages can happen unexpectedly. Factors such as overuse, inadequate supply, and even the weather can cause outages. This can especially be true in areas like Hamilton, Ancaster, Brantford, and Stoney Creek with proximity to the lake and along the Golden Horseshoe. A home generator can provide peace of mind during storms and grid disruptions, but safe, code-compliant installation is essential before purchasing or installing a system.

Determine Your Power Needs
Not all generators are the same. Start by deciding what you want to power during an outage:
- Essential appliances (fridge, furnace, sump pump)
- Heating or cooling systems
- Home office equipment
Knowing your power needs helps you choose the right generator size and type — standby or portable — and prevents overloads. Proper sizing ensures your home generator can safely handle your electrical load without damaging equipment.
Types of Generator Setups
Standby Generators
- Permanently installed outside and connected to your main electrical panel through an automatic transfer switch
- Start automatically during outages
- Ideal for whole-home or large-load coverage
Standby generators provide seamless backup power and are the most reliable option for long-term protection.
Portable Generators
- Movable units that power selected circuits or appliances
- Manual startup required
- Best for smaller loads or temporary backup power
Portable generators are more affordable upfront but require careful load management and proper connection.
Planning Your Generator Installation
Installing a generator safely requires more than simply placing it in your yard. Proper planning ensures the system operates safely and complies with Ontario Electrical and Building Codes.
- Fuel Type: Natural gas, propane, gasoline, or diesel — each has different costs, refuelling needs, and storage considerations
- Location & Base: Generators must be installed outdoors on a level, stable pad with proper clearance from windows, doors, vents, and combustible materials
- Electrical Connection: A licensed electrician must install a transfer switch and properly connect the generator to your main panel to prevent dangerous backfeeding
- Permits & Compliance: All standby generator installations require ESA inspection and must comply with the Ontario Electrical Safety Code (OESC).
These steps ensure your generator runs safely, reliably, and meets provincial electrical and building safety standards.
