Can I Set Up My Standby Generator? (A Complete Guide)

A standby generator provides backup electricity when the main supply fails, kicking in within seconds to keep lights and essential equipment running. Setting one up is not a casual DIY project, so here is what you should know.

Standby generator basics

Standby generators are automatic backup sources available in types from inverter units (1 kW to 50 kW) with features like remote monitoring and reduced noise. They run on natural gas, propane, or diesel and switch on automatically when grid power is lost.

Choosing the right size

Calculate the power requirements of all the appliances you want to run, then choose a generator that meets or exceeds that total. A 100-watt bulb is 0.1 kW, and a 1,000-watt water heater is 1 kW. Add starting wattage for motor-driven appliances and size up accordingly.

Coverage options

• Essential circuit coverage: protects emergency lighting, fire and smoke alarms, telephone or VOIP, and all refrigerators, freezers, and cooling units.
• Managed whole-house coverage: connects to your main panel and automatically powers your entire home, but should be installed by a professional.
• Complete whole-house coverage: protects your entire home from outages, supporting critical equipment and guarding against high-voltage surges from lightning.

Choosing the right location

• Place it in a dry, secure location.
• Keep it at least 10 feet from the house.
• Keep it clear of trees, fences, and other obstacles.

Plan the installation

A well-planned install sets the unit up for years of reliable operation. Decide on your fuel type and ensure proper ventilation, especially for diesel, whose fumes are flammable; never fill the tank more than two-thirds full to allow for expansion.

Find the right professionals

Hire a licensed, insured electrician experienced with generators to size and place the unit and wire it to your panel. For gas units, use a licensed mechanical contractor to handle the fuel line safely.

Delivery and preparation

Generators are heavy and bulky, so ensure space and level ground for delivery, plus the right tools for the install.

Servicing and maintenance

After install, service the generator regularly; smaller occasionally used units may need monthly or annual service, while larger units may need more frequent servicing. If anything seems off, contact an expert right away.
