EG4 › AC output / EPS inverter stage
Neutral-ground bond missing or doubled after install
manufacturer says
Symptoms
- Neutral to ground reads open (about 1.5 megohm in EG4's own demonstration) on a unit that should be bonded
- On a paralleled split-phase pair current flows on the ground conductor between the inverter cases and there is a difference of potential to touch
- An installer's shop fields calls where the bond has silently gone missing from inside a 6000XP or 12000XP
