4000 watt electric setup

[SourBubbler]

Whether the dryer circuit works depends on the circuit arrangement. The 3-wire 240v mentioned above will actually have 4 wires total at the receptacle - there is also the ground to account for. If there are only 3 wires in the receptacle, then a neutral is not present - just 2 hot legs and a ground.

If 120v is all that you need, then the receptacle wiring could be re-arranged even if it is straight 240v by moving one of the hot wires from the breaker to the neutral buss. Of course, if it is a 4-wire style then it would be usable "as is" by using only single-pole breakers in your cord-connected subpanel.

Be aware that if a hot wire is converted over to a neutral, white "phase tape" should be used on the wire at each end to mark that it has been converted to that purpose. Also, the receptacle should be changed over to a Nema 5-30 configuration so that a 240v appliance cannot be plugged into it.

The timer would not be needed, but some downstream circuit protection is required if the downstream components are the usual 15a variety.

Wow, okay, thanks. WAY over my head, I'd have an electrician do it before I took the risk. I don't trust myself. Thanks again!
