Anybody replace a transfer switch?

Anybody ever replace a transfer switch?
My brand new Precept's transfer switch took a crap. Jayco is overnighting me a new one.
Is it a simple install, or have a pro do it?

If you are replacing with the same type unit, I dont see why you couldnt do it yourself. Just ensure you have all the power sources isolated. I.e disconnect shore power and batteries. Check the wores you are dealing with are de-energized. I would attempt it myself.

The critical component, if you have it, is the auto start circuit. As TX_Arvee said turn every thing off and I would also take a few pics with my phone to see what wire goes where.

The difficult part as long as your transfer switch is easy to access is the stiffness of the wires. They are heavy gauge and difficult to bend around to get them where they go. I have replaced mine twice. The first time the wires leading out of the switch to the trailer breaker panel were burned so I had to cut them back and restrip. This was a different brand of switch also. The second time I also had to cut the wires back and restrip and they are now much shorter. If this happens again I will have to replace the wiring from the switch to the breaker panel. Not looking forward to this.
