I want to wire an 8 kw standby generator to power my home furnace (120 v, 20 amp) automatically in case of a power outage.
The generator can be purchased with and without a transfer switch.
Is there important circuitry in the transfer switch (e.g., that starts the generator every week so)? Or, can I just wire the furnace to a double pole double throw relay, for $20 or so?
(I plan to run a few extension cords to power lights, refrig, etc. but I will hook those up manually.)
