These aren't as common as interlocks or solid-neutral switches, but are made by Eaton (CHGENxxxxxSN models) and Reliance Controls (their Panel/Link X-series - the regular Panel/Link units have a solid neutral), and combine a special switching neutral transfer interlock with panel spaces for standby loads. This situation of dueling neutral-ground bonds leads to objectionable stray current on grounding wires and will trip the GFCI on a generator with full-panel GFCI protection, even.Īs a result, you'll have to jettison the interlock kit approach in favor of a switching neutral transfer switch or panel.
