For an above ground pool:

1) How far can the heater and filter be placed from the pool?

Article 680.12 states "...Each means shall be readily accessible and within sight from its equipment and shall be located at least 5 ft horizontally from the inside walls of a pool..." If I am reading this correctly, if the disconnect for the heater, and the heater, are located 25' from the inside wall of the pool, this would be acceptable, correct?

Article 680.22(A)(1) states "...Receptacles that provide power for water-pump motors or for other loads directly related to the circulation and sanitation system shall be located at least 10 ft from the inside walls of the pool..." If I am reading this correctly, if the filter receptacle, and the filter, are located 25' from the inside wall of the pool, this would be acceptable, correct?

2) Is a double receptacle GFCI outlet acceptable for the filter, or does it need it be a single receptacle?

3) Can Romex be run within the house from the main panel to a box outside, then run THWN from the box, in conduit, undergound, to the disconnect box for the heater, the filter GFCI outlet and the GFCI maintenance recepticle? Or should it be THWN, in conduit, the entire way?

4) The heater specs call for a 60A maximum fuse size, and Mimimum Circiut Ampacity of 35A. So this would require a 60A breaker, and 6 AWG wire, correct?

5) I understand the filter and maintenance outlets require GFCI protection, but what about the pool heater? Does the pool heater require GFCI protection?

Thanks in advance.

1. since 25' EXCEEDS the 5' minimum, it is obviously acceptable.
2. It is a GFCI protected so you can have as many "receptacles" as you want, as long as they are in series.
3. As long as the "Romex", (and the company will have a problem with you if you use any other brand), is protected you can use it.
4. IT does NOT "require" a 60 amp breaker. It requires one between 35 AND 60 amps.
5. Are you going to "plug the heater in" or hard wire it?
6. Do not forget to "ground" or "bond" everything, including the pool's framework.

Thank you HJ.

With regards to the Romex, by protection are you referring to GFCI protection?

Can you explain why a 35A-60A is required although the heater specs call for a 60A maximum fuse size? And what gauge wire is then required?

The heater will be hard wired.

Bonding - #8 solid copper wire attached to the pool wall (18-24 inches from the pool and 4-6 inches below grade) at 4 uniformly spaced points. The heater and filter will be bonded to this as well as pool water by way of a filter bonding kit. The ladder is all plastic, and no lights.

1) The equipment can be as far from the pool as you like. When you get close, like 6'-10' then things get more stringent.

2) As long as the filter is more than 10' form the pool a standard GFI receptacle is fine if that's what you choose. If between 6-10' form the pools it must be a single and locking type (twist-lock) receptacle.

3) Standard NM cable/Romex can be run for this equipment within the structure of the house. Once you penetrate outside you must have conductors in conduit with a green insulate ground. The only thing this does not apply to is a pool light. That MUST be in conduit back to the panel.

4) Technically you can run conductors capable of 35A, and the breaker can be up to 60A. Depending on the distance I'd run #8 NM cable on a 40A breaker.

5) Unless the heater plugs in, or the manufacturer specs call for it, no GFI protection is required.


There are quite a few changes for pools in the 2014 NEC, but NYS is not under the 2014 NEC yet.

No help for the OP but question from a novice - Why does a pool require a green ground and not the bare ground from the romex?
