Question: I have a whirlpool tub ( 1 HP) on a 20 amp circuit, 12/2. The receptacle is located 3 feet from the motor, can I use a duplex receptacle or do I need a single receptacle?

Table 210.21(b)(2) Maximum Cord-and-Plug-Connected Load to Receptacle (receptacle means 1) has a single receptacle rated for 20 amps but the maximum load is 16 amps. A duplex receptacle is rated for 20 amps, maximum load is 20 amps.

110.3(b) Instructions requires a dedicated circuit, 20 amps

Section 210.23 (A)(2) Utilization Equipment Fastened in Place The total rating of utilization equipment fastened in place, other than luminaries, shall not exceed 50 percent of the branch-circuit ampere rating where lighting unit, cord and plug connected utilization equipment not fastened in place, or both, are also supplied

Does it have to be GFCI?

Almost always, yes.

Anyway a 20 amp duplex will be OK. But not a 15.

I disagree. Unless the load requites a 20-amp receptacle (i.e., a T-slot), a 15-amp duplex is permitted. A single receptacle is not required, but if it is used, then it must be a 20-amp receptacle.

Is it a 20 amp cord connector?

If so, then, of course, the receptacle, whether single or duplex, must be rated at 20-amps.

By the way, "dedicated circuit" need not mean a single receptacle. A laundry circuit is an example.
 
Hi ju I would put on its own circuit , dont have time to visit the customer about dimming lights , keep him happy!!

680.71 requires that the tub be GFCI protected.

The tub requires a 20A circuit as per instructions.
A 20A single or duplex device could be used.
