In planning the installation of a KM600 Hoshizaki with remote condenser I had the customer arrange with his electrician to run a 20A-230/115V 4-wire circuit to a disconnect on the wall next to where the machine was going. I wrote it down for him and further explained that I needed 230V with a neutral for the 115.
I get to the job and see the box labeled "115V 20 amp 2 circuits".
I checked the panel and see two new single pole breakers. I check at the box and then find that Sparky plugged his breakers into the high leg....on both of them, so I'm getting two hundred something volts to ground and zero between (cause they're on the same phase).
I get him on the phone and he says yeah, yeah .....they know all about 3-phase and the high leg stuff and he'll send a guy out to check it out.
The next day I go back a find stuff moved around and a new 2-pole breaker but one side is still on the high leg, so I call the electrician back and tell him it's still not right. He says that just make sure that the 115V side isn't on the high leg and I'll be OK.
I don't like doing that and as far as I know the Code allows it, but what can you do in a case like this? Anyway I told the customer about it and noted it on my invoice that in my opinion the machine is improperly wired and will void any warranty either from me or the factory.
What do you think?
