2002 Endeavor bad IIOTA ITS -50R replacement

I replaced my Iota with the WFCO T57 transfer switch. Easy replacement, all wires lined up, very easy swap out. I tried using a Powermax but the wires had to be crossed over to installed and it's not easy to move them.

For a superior switch consider the PD53-100.

I looked up IOTA and found the same WFCOT57 switch as above. They aren't that exotic and pretty much looks like the IOTA.

Huh, I didn't know Iota went out of business. Must have been the recalls.

Doesn't sound like you have much choice but to retrofit another brand. This WFCO claims to be the direct replacement:

WFCO T57

Unless your wire lengths are really tight, or space where it is installed is very tight, any will work. Every one of them has exactly the same connections (two hots, neutral and ground) in from both shore and generator and the "outs" to the coach main breaker box.

If in doubt about whether the box will fit and/or wires will reach, compare on-line pictures/dimensions with what you have.
