Transfer Switch
Hello,
This question is on a Winnebago destination 5th wheel.
It has a automatic transfer switch that was pre wired for an onan generator from the factory. I do not have a generator installed. The switch is making an increasingly loud humming noise. I checked for loose wires and all is good there. I have decided to either remove or replace the switch. We are planning a trip very soon so I will not have time to replace it, and because I do not trust the switch due to the noise I have decided to remove it for now. I have all the proper connectors and tools to do the job just need to, and am about to ask a dumb question.
The switch has main wire going in and one coming out, so can I, after shutting off all current to the Rv , just wire black to black , white to white ETC ETC.
I mostly read a gather info on here, so any advise on this will be appreciated.

If you Abe an inverter be sure it is off. Do no be on shore power.

It has small inverter, that will run the residential frig, but if I use the battery disconnect along with no shore power I should be good to go with my plan, correct?

Inverter only provides 120v upstream on dedicated circuit[s], so no real issue there. Many x-fer switches are based on AC [verses DC] power to actuate the contactors. Overtime, these AC powered contactors will begin to chatter or vibrate in unison with the 60 cycles associated with AC power. Bothersome to you but probably not an issue. As indicated, re-wire/by-pass if you think it would provide peace of mind.

You'll be fine with just the shore power off.
Turning off the inverter is a safe practice but the inverter will not back feed to the main transfer switch.
The inverter has its own transfer switch to prevent that, otherwise it would try to power the whole RV.

Every electrical wire is considered energized until it is confirmed safe by a dependable volt meter. People without that basic tool should never touch an electrical circuit. Far too many people test fate with electricity.
Ok, bring on the attacks, but l speak from years of experience. Make your own decisions and take your own risks.

X2!! If you have to ask questions a digital volt meter and knowing how to use it will keep you from taking on 120 volt and staying out of trouble.
