Daikin, Manufacturer of a heat pump, wants to have a circuit protected by a 240 v. GFCI cir. br. feeding power to the EXO which has two 20 amp fuses in it. Does anybody out there know why they are asking for this? Does the NEC require all EXOs to have GFCI protection now?
No response from their email. No phone number for tech support.

Sounds like a manufacturer recommendation. I have never seen a heat pump on GFI, assuming an EXO is a ground water source heat pump?, that is up to the spec sheet. But still even those just get a regular breaker.

Per 210.8(A)(3), all 15A and 20A, 125V receptacles outside of a dwelling unit has to be provided with GFCI [Ground-Fault Circuit-Interrupter Protection for Personnel.]

I think NEC requires a receptacle outlet:
210.63 Heating, Air-Conditioning, and Refrigeration
Equipment Outlet. A 125-volt, single-phase, 15- or 20-
ampere-rated receptacle outlet shall be installed at an accessible
location for the servicing of heating, airconditioning,
and refrigeration equipment.

I don't think the OP is talking about a 120 volt receptacle, not sure what an EXO is but it apparently is 240 volt and has two 20 amp fuses in it.

Hmmm

Hmmm

Yes Augie....god the bloody acronyms....
Even at large they have been taken too far.
How about people start using words again so some of us can come up to speed.
Going on 30 years in HVACR and I have never heard that term, but I may not be up with current affairs.
? Electric Heat Accessory?............
This is a 3rd rate OEM.
I have to wonder what they are trying to " protect " and why this angle. What brought it about exactly.
