Travel trailer or 5th wheel?
30A or 50A??
I have a 5vr....50A
OEM shore power receptacle (Marinco Twist lock) is at rear/curbside
I installed a 50A Marinco Twist lock receptacle on front under overhang curbside.
I cut the power cables in to from rear inside the basement area. Power cables came out of distribution panel and went into basement compartment then rearward to OEM receptacle.
I installed a transfer switch so that only one receptacle was HOT at a time......dangerous to have them both HOT.
The OEM cables went into the transfer switch....input side
The main panel cables went into transfer switch....output side
The new cables from new front receptacle went into transfer switch...input side
I was able to do all wiring connections etc. inside the basement compartment.
When power is applied the transfer switch swaps to that source.
This was great for 8 mos. when transfer switch failed. Parallex shipped me a new replacement--warranty. The new one was faulty upon arrival. Called them....they said "Yeah we've had problems with the relay/contacts...can you ship them back to use for troubleshooting? We'll send you another one" :S
Forget it........we full time and not having power after 5 days needed to do something NOW.
Bought a 125A sub-panel and two double pole 50A breakers with a mechanical interlock bar, some 6 gauge wire and three electrical junctions boxes.
(Had to use junction boxes due to power cables being to short to reach where sub-panel was mounted in basement compartment.
OEM rear power cables go to one breaker
New power cables go to other breaker
Main power cables come off bus
When plugged into front....flip that breaker ON....interlocking bar trips other breaker. When plugged into rear.....flip that breaker ON...front breaker trips
No transfer switch to fail again!
How ever you do it.....you need to isolate the two sources so that only one can be HOT at a time.
If you can't run the power cables inside..then run then under attached to frame inside conduit for protection then up into rig.
Good luck.
