PowerProtect home standby generators

Every spec sheet behind this table marks the unit cUL as well as UL, and every product page says the generator is rated or listed to UL 2200 and to CSA standard C22.2 No. 100, in its 2014 edition. The PowerProtect 18 kW has no spec sheet, so its row rests on that CSA statement alone. On natural gas, the 26 kW units drop to 24 kW and the 13 kW units to 11.5 kW, while the 18 and 22 kW units make the same power on both fuels. For a home on the gas main, read the natural gas column when sizing.

The newer spec sheets give minus 1 °C as the lowest operating temperature with no warmers fitted, and minus 28 °C once the cold start battery and the battery, fuel regulator and oil warmers are installed. The older sheets give minus 28 °C without that condition. Every sheet lists an engine oil heater or warmer as an accessory, and the transfer switch page sells a cold weather kit, with a battery warmer and two oil heaters, for select home units of 10 to 26 kW. The electrician can fit these during the installation.

Briggs and Stratton sells these generators without a transfer switch, so the switch is chosen with us for the home's electrical service. A service entrance rated switch is wired in after the utility meter and ahead of the panel, so the utility must cut the supply and restore it afterward. A licensed gas fitter runs the gas line and confirms the meter can carry the generator. Before a generator is wired in for good, the Electrical Safety Authority (ESA) has to receive a notification of the work, and the transfer switch stops the generator from feeding power out onto the grid.

The Electrical Safety Authority (ESA) notification of work is filed before the work starts. When the installation is done, ESA inspects it and issues a Certificate of Acceptance once it passes. Where the unit burns natural gas or propane, a licensed gas fitter makes the gas connection. Where a meter or a service entrance switch is involved, the local utility does its part of the work.
