Can HS200 (HS210, HS220) switches operate properly in cases where the neutral wires for two circuits are joined? It appears that the electicians who wired this house had a habit of bundling ALL of the white wires in some junction boxes together, creating multiple pathways back to the main panel. As a result, there can be a minimal amount of (phantom) voltage on the neutral wire where the switch is to be installed. Will it damage the HS200 if I test it under these conditions? Would you expect it to affect operation?
Shared neutral wires?
