Maine, it's interesting then that many commercial off-the-shelf bilge pump control panels (like the one below, currently fitted to my boat) are negative switched - that's one reason so many people have problems hooking them up!

1. Are you saying a commercial purpose-built product doesn't meet the standards??

2. Do you seriously expect a competent surveyor to inspect the entire wiring system on a boat - looking for circuits that might be negative switched??

No. I didn't think so.
