Having trouble keeping AC power tonight within the coach. Capturing notes/thoughts here so I remember them in the morning and to add the solution once I figure it out tomorrow
Had no hot water this morning. Traced to a tripped AC breaker for that circuit. Reset breaker - all was well. Tonight, fireplace shut off. Traced to tripped AC breaker for that circuit. Reset breaker, it held for a few seconds and tripped again. Reset it again and the main 50 amp breaker in the AC panel tripped.
Looked at PCS (power control system) panel and it showed good AC power on both legs with 7 loads shed. There are 7 AC using items that are controllable by the PCS - so all were shed.
Looking closer at the PCS panel, it was showing 0 amps on L1 and 106 amps on L2 and 106 amps total. Huh? How can it allow 106 amps to be drawn on a 50 amp circuit?
Reset 50 amp breaker and power came back on to all non-PCS controlled circuits. PCS tried to unshed the shed loads and they re-shed with some buzzing behind the AC panel.
Now PCS panel read NO POWER - meaning no incoming AC power. I thought I had a glitch in the PCS with the 106 amp reading and now reading NO POWER to the panel. I went outside and shut-off the 50 amp receptacle breaker, waited, then turned it back on. I heard the ATS (automatic transfer switch) clunk like it switched over to shore power. Came back inside, still reads NO POWER.
At this point, I'm now thinking I have an issue at the ATS. For safety, I'm unplugging the coach for the evening. We'll use DC lighting and the propane furnace and I will tackle this tomorrow and report back. If it's the ATS, I could be unwiring it from the circuit and splicing the mains feed to the AC panel feed until I get a replacement ATS.
Up to this point there's been no other issue with the PCS or ATS, so who knows...
