A 1500 watt inverter is capable of drawing close to 150 amps. Neither of the two connection you mention would be sufficient. In addition such high currents would probably damage any BCC conductor paths.

I'd recommend to connect both positive and negative of the inverter DIRECTLY to the battery terminals using 00 size cable. Do not use the chassis as a return circuit!

On the positive cable, an appropriate sized fuse within 18 inches of the battery terminal should be used.

Yes, On the BCC for my rig, that 30 amp breaker is where NRV had wired in the their optional 600 watt inverter. That provided 120 volts output to the entertainment outlets in the bedroom and the entertainment center up front only. These outlets combined would have to use less then about 3amps to stay below the 30 amp breaker limit on the BCC. If I were to connect a 1500 watt inverter in the same place, I would have the same limitation of about 3 amps total at those outlets.
If your coach is not pre wired for the optional inverter, I would suspect it does not have the additional ac wiring mine has which prevents the inverter from coming on unless there is no shore power or generator power present.

That is what I was trying to do, so if I got a 600 watt inverter I would still have to install a new breaker and rewire the plug for the tv in the front over head compartment, Im sure it was not pre wired for an inverter the breaker box inside dosent list a inverter.. Can I wire a 600 what inverter to that 30amp side to find out if it would work, just a thought....

Hard to say. Depends on what your MH wiring is for the 2001.

My discussion below is based on the 2003 wiring diagrams. I suspect it applies to yours too. Some where on this forum or on some other NRV forum there should be access for you to get the NRV wiring schematics.
If all your going to do is power up your tv, any size inverter will work that exceeds the tvs requirements in watts. and yes the 30 amp breaker on the BCC is where you can connect to. Be aware that some means of isolating the inverters' output from other possible ac sources must be provided.

The 600 watt inverter NRV installed and I removed has a built in transfer relay. When normal ac is present, the inverter is completely bypassed. When no ac is incoming, the relay disconnects the inverter from its ac source and allows it to become the source to the branch circuit it is connected to(tvs). This happens when no other ac is present and the inverter is set to be on.

NRV modified a duplex outlet, the one that the converter is plugged into. It also is a junction point which feeds the tv outlet in the bedroom as well as the outlets in the front entertainment area. In that duplex box, the branch feeding out to the tvs is wired out of the box via a zip cord that plugs into the inverters' ac outlet. The inverter ac input is plugged into the other half of the duplex receptacle.

When ac is supplied by way of shore power or the genny, The inverters' transfer relay passes that power straight thru the inverter and back into the zip cord.
When no ac is available, and the inverter is allowed to be on, the transfer switch disconnects its ac inputs and then supplies inverter ac to the zip cord thus feeding the tvs.

Look at your electrical compartments arrangement. Find the ac connection to the converter. If in addition to the converter plug, there is a second plug that wires its self back into the same junction box, then your prewired.

If not, this is the location that may give you access to the tv circuits.

Thats a great resource. But it doesn't show the detail of the ac circuit in my post above. The NRV drawing number that does is 550-39-00026 which may be specific for 5342 models. I will try to scan it in and post it somehow.

Yes, there is another plug it feeds out the other side and goes up inside in the front compartment I assume... That wiring diagram looks to be the one that I have... Thanks alot guys, I owe you a cold one......

Below is a link to the members Gallery, where I posted pictures and Info on my install of a 2000 watt inverter , when I added solar. I added a separate breaker box and divided my electrical groups . I also added two extra batteries to the system. Try to get the schematics for your year/rig.
