Church heating AGAIN

[sjwkmje]

I am back at the problematic church heating again.!!!!

This time the contactor has burnt out, which given the fact it is about 37 yrs old may not be that much of a suprise.

Will post some pics later.

The church want me to install a new contactor, which I am sort of happy to do, but a little hesitant at the same time.

The heating is above the ceiling!!! Bizarre I know.

In the ideal world I would want to crawl all over the system, however, due to asbestos I cannot access 90% of the system.

Any ideas/ advice etc, most appreciated

Not sure if this will help or not but I had over heard a simular situation with contactors at work on a lighting install. Worked fine for a few years then the contactor went, new one fitted again went a few weeks later. Turned out to be transients wearing out the switch contacts in the contactors. A snubber was fitted and it worked fine. The transients was caused by the inductance in the circuit and created a nice voltage spike. That was the conclusion I came up with and as I was an electronics engineer at the time I could go get a scope and a 100:1 probe and check.

Could be the same there are large voltage spikes / transients wearing out the switch contacts as something its feeding is breaking down etc.

When we refer to a contactor "Burning out" we are normally referring to the coil burning out - luvly smell! Gets right in the back of your throat

Unmistakable - hits you the second you open the panel or before if it's a good 'un !
