    Has anyone ever attached a plug wire to the HPWC to plug into an existing outlet? Specifically I've got a generator connection to my panel through an L14-30 male receptacle, feeding in/out through a 30 Amp breaker. I understand I would not be maximizing charging ability, but could still access 240V at lower amperage. Thoughts? Thx!

    I did it with my siemens versicharge, don't see why it wouldn't work. Neutral not needed so don't confuse neutral and ground on that round plug. Ground is needed for ground fault self test.

    What gauge wire did you use, and what capacity breaker was in the box?

    If you have a plug that is a generator plug, then no, it shouldn't work, because it would be feeding the wrong side of switchover switch.

    But be aware, that while it would work if it isn't connected to a switch, then if someone does plug in the generator, then if you forget to throw the whole house breaker, you could cause, lots of damage, fire, and death.

    Ohhh did you say MALE receptacle? That should be isolated by a transfer switch in which case, it'll have no juice on it. If you mean to plug into a generator using the female receptacle on the generator, sure.

    Thanks for the insight. It's not worth the risk, therefore I'll have an electrician hardwire.
