A security system installer,told me he attended a class in Massachusetts and was told by the instructor that the panel cord can be supplied by a non gfci protected single receptacle even in an unfinished basement. He also told me that in one town in Ma. the inspector failed him because the receptacle was gfci protected.

I looked at the Ma. amendments and can find nothing. Anyone ever hear of this?

Take a look at the Exception to #5 in 210.8(A).

I don't know if MA has amended or changed this section.

Thank you I guess he is correct. I didn't finish reading that exception I stopped at fire alarm.A lesson well learned.

The answer was already given NEC wise and I looked at the Mass code and found no change.

The inspector failing because the receptacle was GFCI protected is rather odd.

It's beyond odd, it's wrong, and I've never heard of such a thing. He doesn't have the authority to "ban" the use of GFCI without some kind of possibilty of disabling some kind of safety equipment.

I agree with you. I have found burglar alarm control panel with the cord (transformer) plugged into the gfci recpt.on the service panel board,taking up the space of the required gfci protected receptacle(210.8(A)(5) I wonder if the inspector failed it because of that,and wanted a new outlet for the burglar alarm? It seems unreal to me that the inspector would not permit a gfci protected receptacle.

I should have added 210.52(G)
 
760.41(B) and 760.121(B) "An individual branch circuit shall be required for the supply of the power source. This branch circuit shall not be supplied through ground-fault circuit interrupters or arc-fault circuit interrupters". Similar requirements in NFPA 72.

That applys to fire alarm systems but not to security systems. The original poster was asking about a security system.

Does not apply to security systems. Plus a transformer has the retaining screw that only works with a duplex receptacle, not a GFCI type.

Alot of the plug in transformers that I am seeing today don't have the retaining screw anymore.

Also, with the fact that decora style receptacles are becomming more and more common place the retaining screw wouldn't work on these receptacles either.

If the transformer is plugged into a duplex receptacle at the panel board in an unfinished basement would the exposed half of the receptacle need to be gfci protected?

I tell the electrician to break the taps off to de-energize half of the receptacle.
