What's different about generator installation in Portland
A portable generator through an inlet and interlock can keep heat and the refrigerator running, and standby units suit homes with space and a fuel supply. Generators must run outdoors and stay clear of snowbanks and windows. Permits come from the city's permitting and inspections department.
Older homes often have knob-and-tube, small services and several units on one building service. Heat-pump conversions and EV chargers frequently start with a service upgrade.
