Well the whole issue here is that we have a generator cord rated 30AMP 240 (4prongs) and we were wondering if we can use that cable & install a 30Amp 240V Outlet to have 2 trailer plugged with full 30Amp.
I see that there is still a split decision whether "yes" and "no".
We are planning on installing a 50AMP 240 and have the "Y" adapter to 2 30Amps 120V but since we have the generator cord that could save us a ton of funds that can be very useful for some aluminum...
If you are installing a 50 amp circuit, you should add a sub-panel with breakers, not a 50 amp plug with a splitter adapter. You probably could rig something using that 30 amp cable that would work, but it might be dangerous.
1. You should get a qualified electrician to do the work if you are modifying any portion of the existing permanent electrical system you are connecting to. Or, if just plugging into an existing outlet, have someone look your work over before you power it up. You could damage your home and/or your trailer.
2. The chord you have for your generator should not be used as permanent fixed wiring inside your house or garage. It is meant to be a temporary drop chord.
3. If you spit the wires on a 240v 50 amp circuit without using breakers to protect any extensions from it, you will have 50 amps on the wires rated for 30 amps. The chord is probably has #10 wire rated for 30 amp.
4. The 240v circuit is protected by a double pole breaker. A 120v circuit extended from a 240v circuit should be protected by a single pole breaker with amp rating no larger than the amp rating the wire extending from it.
