FAQs
Why does my generator run without powering the house?
The cause may be generator output, protective devices or transfer equipment. A running engine does not confirm that a safe electrical connection is working.
Can I plug the generator into a home outlet?
No. Backfeeding a home through an ordinary outlet can endanger occupants and utility workers. Have a qualified installer assess approved transfer equipment.
