Anyone know if the power from my 10kw gen goes to a junction box somewhere in the coaches front area?
On my 1999 U320 36' it looks like the generator output goes to under the bed to the transfer switch where after switching between shore power and generator it then goes to the breaker panel.
Bob,
My 1995 U320 goes straight to transfer switch under the bed.
No front junction box?
The wires go directly from the generator to the 2 45 or 50 amp breakers in the control box depending on your model then conduit to the ATS
Thanks
My 1996 U320 has a junction box on the back wall of the gen compartment with flex conduit coming from the gen control box mounted on the gen.
CaFlashBob, Did you go look at your coach to find out what is there for yourself? The only right answer is what is in YOUR coach and only you can answer that by looking for yourself.
We did look. We did not see a j box. Like Cunard and the Space Shuttle Foretravel probably learned not to splice any wires unnecessarily. Just wanted to see if we maybe missed it.
We are wiring a "buddy" plug into the gen output in that front area.
Setting up our home to be able to be powered by the coach in an emergency.
Sub panel, disconnect box....

This does not make sense to me. On my 1996 U320, the wires (2 hot & 1 neutral) from both "the generator" and "the shore" are the input wires to the "ATS" while the output from the "ATS" goes directly to the 50amp main breakers in the Main 120VAC "Power Panel". I am unable to understand how generator wires going directly to the 120VAC Power Panel would work.
Caflashbob:
If you use your generator output for emergency power to your house, there will not be 240VAC power available without rewiring the output from the generator. This is because the two hot generator output wires (one from each armature) are shorted together at the generator, than connected to two hot wires ( one red & one black) which go to the Genset/Shore "ATS". This shorting of hot wires at the generator requires that output from the two armatures are in phase and are 120 VAC each. This hot wire shorting at the generator is required so that the voltage control which can only be on "one" of the armatures will work.
I think craneman is referring to the "breakers in the control box" that is physically located
on the generator - not to the 120VAC Power Panel.
That is what I was referring to. When I installed the new generator head that is where the wires went.
My buddy says the powertech gen pigtails into a junction box behind the unit.
We are going to install a buddy 50 amp plug in the front of the coach.
May be safer to wire a buddy plug from the main breaker panel, where the buddy plug can be protected with normal circuit breaker and kept turned off when not needed.
If using a buddy plug for another RVer, breaker may be better a little lower than 50-amp to keep them from using all the power.
If for home backup, use 50-amp.
