I am going to feed a 200 amp residential panel with a 20 KW generator. Three large loads will be controlled with DLM modules. In addition I need to feed a 100 amp subpanel that is fed from this same 200 amp panel. I plan to use the priority one 120 volt output to control a 100 amp contactor with a 120 volt coil. A DLM module is only good for switching 50 amps. The actual normal load on this circuit is normally just a few amps and occasionally bumps up to maybe 30 amps when drying clothes, but I can't use a relay that is rated less that the circuit feeder. What have others used in a case like this?
Most relays or contactors I've seen that can handle this load are three phase and VERY expensive and they don't come with an enclosure.
In case you are wondering the subpanel feeds a few lights and bedroom receptacles plus an electric clothes dryer and a steam unit. The steam unit has not been used for several years but the owner does not want it disconnected.
