Dear Mr. Electrician: I want to have a portable generator connection for circuits in my house such as the furnace, the sump pump, and the refrigerator. How can I install this?
Answer: One simple installation is a stand-alone generator sub-panel for some previously selected circuits to be powered when the generator is on. Below are photos of a generator sub-panel installation with a PB-30 generator inlet. Some of the applicable articles from the National Electrical Code concerning the installation of generator sub-panels are: 210, 230, 250, 300, 310, 314, 334 and 702.
