Hello and Happy Holiday’s everyone. I am going to check my neighbor’s sub panel main breaker that is located in the main panel in the garage tomorrow. It has started to trip on several occasions and shut’s down the entire basement and his office. I told him it was probably loose or a bad breaker. I also wanted to test the Temperature of the breaker if it loose to see if it’s overheating. I don’t normally do this, so what temp would I be looking for on a 100 amp sub disconnect?? any help would be greatly appreciated!!!
You are going to check the disconnect or OCPD for the load side panel? The disconnect is located in the service equipment?
As others mentioned, it’s likely there’s actually an over-load or short somewhere. Checking the temp of the breaker doesn’t tell you whether it’s a poor connection or an over-loaded circuit - it will only tell you the temperature.
