Hello electrical guru's / Sorry, I actually posted this in the wrong forum since it is a SFR question. My bad, I didn't realize there was a SFR electrical forum, until now. Perhaps I can also provide a bit more perspective.
Honeywell F300E 1035, replacing an existing F50F electronic air cleaner. Duct mounted, same size, virtually a direct replacement. The current air cleaner is powered with 240V, the heating contractor says the new one needs to be powered with 120V plug in source of power with a dedicated curcuit. I can't finad a code reference in the NEC that requires that. The manufacturer says power can be supplied with either 120V or 240V.
I have been unable to locate anything in the NEC that would prohibit the 240V or prohibit the power source to be the same circuit that supplies power to the furnace itself, just as is the case with the current installation.
In short he has said that a new 120V dedicated line with a plug in recepticle is required to install new Honeywell duct mounted electronic air cleaners.
What say you?
