The FIRST thing that needs to be done is verify that you do INDEED have TRUE 50 amp service. Take a voltmeter and check the voltage between the 2 hot leads at the CG 50 amp plug. It should be 220/240 or double the line voltage. IF it does not read double, then you are NOT on 50 amp service(100 AMPS TOTAL) but on a single phase 50 amp breaker. This would be the cause of your PI dropping out. Doug
It's not 50A RV power but that will not cause the PI unit to drop out. 0V between the 2 hot legs is OK and it's a necessary design constraint in order to be transparent when using a 20A or 30A power with adapters.
ABSOLUTELY WRONG. 50 AMP SERVICE IS DOUBLE THE LINE VOLTAGE BETWEEN THE HOT LEGS. 0 volts indicates same phase and just a single 50 amp breaker. The "Drop" I stated for the PI is IF the line voltage drops below a certain threshold (what the PI is set at), the PI will drop out and that is what the OP is experiencing. The fact he reposted and said mornings it works but evenings it does NOT, indicates LOW CG line voltage. AND, if Correct REAL 50 amp service, then line voltage should not be happening. Doug
Probably some word smithing is required. If a single hot is connected to both 50A hots then it's not a correctly wired 50A plug which is how I interpreted your post but if a plug is wired that way PI unit will connect ie with 0V between L1 and L2.
But if one hot is 0V and the other 120V then the PI unit will not connect. This could be due to a bad connection or loose wire.
