Iota automatic transfer switch

Well we almost had a fire today. Our automatic transfer switch overheated and melted some wires. We know we need a new Ats but wondering if there is anything we can do to replace the wires that have melted. Canít get a new box until at least Wednesday. It looks like the wires that melted are just jumper wires. I have attached a picture of what they look like. Thanks for any help.

If you don’t need the transfer switch capability, then just parallel the genset or tether incoming power wires with the coach side power side wires.

Perfect example of why people need to check and tighten any screw clamping type of electrical connections in their coaches. It’s very obvious why this panel burned up.
I would strongly advise you to open up your breaker panel and check ALL wiring connections within the box - blacks at the breakers, whites and ground at the buss bars.

The white wire that I've marked with the red arrow , appears to have enough slack to allow cutting off the damaged end and connecting to the new ATS buss bar ,
The red wire's insulation ; yellow box ; is melted and the wire has to be examined for damage , if the wire is damaged then finding enough slack could be a problem ; if only slight melting ( wire not exposed ) then wrapping with tape would do .

After the new ATS is installed and systems have been used for a short period , then an electrical system shut down an re tightening of all the screws is in order and add tightening of the screws to your annual maintenance list.

The damage looks like it could be extensive enough that you may want to just bypass the ATS until you can replace it.

What were you using, generator or shore power? It would not be too difficult to temporarily splice the feed from whatever source you were using directly to the load side.

There has been a thread on the site of a similar failure.

It is important for people to know that there was a recall of the Iota ITS-50R back years ago but in a lot of cases they never got changed.

I'd recommend all owners of older RV check their transfer switches.

In my case, I own a 2002 Monaco Windsor built in late 2001. During the build year they did a parts change, any Windsor built before Aug 2001 would probably have the Iota, my rig came with the Lyght LPT50BRD.

I just started to follow the thread on the Monacoers group. My rig has the IOTA, ordered a new ESCO unit Friday, will replace the IOTA ASAP. If anyone is looking for the ESCO at a good price, here is a link to where I got mine.

That is the same one I am looking at. We have a gas 2005 holiday rambler. How do I know it will work with my system?
