680.7 Cord-and-Plug-Connected Equipment Fixed or stationary equipment, other than underwater luminaires, for a permanently installed pool shall be permitted to be connected with a flexible cord and plug to facilitate the removal or disconnection for
maintenance or repair.
(A) Length. For other than storable pools, the flexible cord shall not exceed 900 mm (3 ft) in length.
(B) Equipment Grounding. The flexible cord shall have a copper equipment grounding conductor sized in accordance with 250.122 but not smaller than 12 AWG. The cord shall terminate in a grounding-type attachment plug.
(C) Construction. The equipment grounding conductors shall be connected to a fixed metal part of the assembly. The removable part shall be mounted on or bonded to the fixed metal part.
680.8 Overhead Conductor Clearances. Overhead con- ductors shall meet the clearance requirements in this section. Where a minimum clearance from the water level is given, the measurement shall be taken from the maximum water level of the specified body of water.
(A) Power. With respect to service drop conductors and open overhead wiring, swimming pool and similar
installations shall comply with the minimum clearances given in Table 680.8 and illustrated in Figure 680.8.
FPN: Open overhead wiring as used in this article typically refers to conductor(s) not in an enclosed raceway.
