I have been in our new house less than 1 year. Yesterday we had a a prolong power outage so I decided to test the generator I got for hurricane season to the house existing generator inlet. I turned off main line Breakerbreaker engaged interlock to isolate Backfeedback feed breaker.

I turned generator while generator breaker and all other breakers are off I connected the 240/120 50 AMP cord to the outside inlet all good. I turn on AC breaker on generator all good. When iI get the to house main panel and attempt to turn on the panels back feed 50 AMP breaker the AC breaker on the Generatorgenerator trips off.

House has the following: -Duromax xp10000eh with floating neutral system connected with Generator Power Cord to 240/120( I don't know what prior owner had) -Reliance PB50 Inlet box wired through - 4 wires(Red, White, Green, Black.) Green connects to Inlet bolt. -Reliance MB125 Indoor 50-Amp Meter Box into (4 wires from inlet red, black, white and coppper) White and Copper connect to neutral bus on pannel, red and black connect to Q-Line Breaker. -MainPanel with Interlock with GE 50 AMP - Q-Line 50 Amp 1 in. Double-Pole Circuit Breaker(thin).

  • Duromax XP10000EH with floating neutral system connected with Generator Power Cord to 240/120 (I don't know what prior owner had)
  • Reliance PB50 Inlet box wired through 4 wires (Red, White, Green, Black) Green connects to Inlet bolt.
  • Reliance MB125 Indoor 50-Amp Meter Box into (4 wires from inlet red, black, white and copper). White and copper connect to neutral bus on panel, red and black connect to Q-Line Breaker.
  • Main panel with Interlock with GE 50 AMP - Q-Line 50 Amp 1 in. Double-Pole Circuit Breaker (thin).

Any ideas, at? At first I thought it was the generator but this generator has a floating neutral. I am not sure if there is a fault somewhere or the breaker may not be appropriate for the generator.
