Replacing transfer switch

[Lindenberg]

The Todd Engineering 50A automatic transfer switch in my 2000 Alpine needs to be replace. I read where Todd is out of business but ITOA took over the product line. ITOA's ITA-50A appears to be the same unit I have. Is there a better transfer switch you can recommend or just replace what I have?

Hello Tom:

All transfer switches are about the same, some have more bells and whistles than others. It all depends on what you want and how much you want to spend. The one installed in my coach is now made by Surge Guard.

I would say that if the original lasted 9 years, and this is an exact or pretty close replacement, it is a good bet.
The other alternative would be a fault limiting xfer switch like Surge Guard. They also make a model w/remote monitor panel.

Just my opinion- I've been in ancient coaches on their original xfer switch, and new Country Coaches with a brand new faulty xfer switch thumping on/off/on/off at an FMCA show. I think when you get one that works, stick with it, then have a margarita

tom,

You didn't say why the unit needed replacing. If the problem is just with one of the contactors (lg relay), they are readily replaceable. If it is with the control, td relay or circuit board, then you have a problem.

I had (2) of the IOTA/50 transfer switches fail...it was in the time delay portion. You can get the TD circuit board from IOTA for around $35.00.

UPDATE: I replaced the transfer switch with the IOTA ITA-50A and everything is working again. The problem I was having was the contacts for the 50A shore power were pitted and not making contact. While watching the transfer switch I could see small sparks coming from the problem contact. I took some fine grit wet/dry sandpaper and cleaned off the contacts then bent the bracket holding the problem contact closer together. It worked but figured a new transfer switch would be the best way to go. The new transfer switch was $130 from the manufacture and was easy to install. I did need to download the installation instructions because none were sent with the unit.
