Compare written standby-generator proposals on the same household loads and site conditions, with equipment, electrical, fuel, permitting, commissioning, and service scope recorded separately.
Generator planning and safety guides
Size, place, operate, fuel, and maintain a generator using measured loads, current manuals, outdoor-only safety, and a realistic runtime plan.
If your portable generator can use both fuels, compare its rated output and fuel requirements by mode before deciding which supply fits your household.
The age of reserve gasoline is only one part of the decision. Separate fuel in an approved container from fuel in an engine, then follow the exact manual and local fire rules.
Gather the exact furnace and blower electrical data, control requirements, and connection questions a qualified contractor needs for an outage plan.
Match a temporary generator cord to one appliance by checking the appliance label, generator receptacle, outdoor rating, route, length, and cord markings.
Prepare for an electrician visit by comparing manual transfer switches, panel interlocks, and automatic transfer systems at a planning level.
