Preventive Maintenance Auto Transfer Switch
Is there any preventive maintenance we should be doing on our Auto Transfer Switch? Heres why I ask - We just had an odd situation. Plugged into shore power a couple days ago as normal, then flipped...

I'll play devil's advocate for a moment and ask what is different between a relay in the air conditioner switching the load and a relay in the transfer switch- other than the transfer relay is the size of your fist, and the a/c relay is the size of your thumb.

Fpr the rare transfer switch with open contacts, I do clean the contacts with Caig deoxit and treat them with progold.
I hope you are just messing with us. There is a BIG difference transferring 30/40/50 amps of load on spring loaded Contac point relays and transferring an AC unit. Remember, the AC comp relay is transferring NO real load, just closing the compressor contac relay, and THEN a few seconds later the Start Capacitor starts the LARGE load required to start and run the compressor. MOST AC units also have a time delay (2.5 to 3.0 minutes) between compressor starts if you try to short start. In other words, you are comparing apples and oranges, not the same thing at all. Doug
