Here is the code section that applies from the UCC
§ 5:23-2.18C Use and occupancy of swimming pools, spas and hot tubs
(a) It shall be unlawful to continue the use and occupancy of a swimming pool, spa or hot tub
until a copy of a valid bonding and grounding certificate has been made available to the
construction official, the pool, spa or hot tub has been inspected, and an electrical certificate of
compliance has been issued. This requirement shall apply to any swimming pool, hot tub or spa
located on any property other than one or two-family residential property and includes, but is not
limited to, pools, hot tubs or spas open for the use of members, residents or the public.
1. The electrical certificate of compliance shall be issued annually by the local enforcing agency upon the presentation of a valid bonding and grounding certificate, satisfactory completion of an inspection by the electrical subcode official and payment of an inspection fee. This certificate shall be
evidence that, based upon a visual inspection, the wiring in or around the pool pump and associated electrical equipment is free from electrical safety hazards, and meets the applicable
requirements of the electrical subcode.
2. The bonding and grounding certificate shall be issued in accordance with
3. A bonding and grounding certificate shall also be required for swimming pools, spas, or hot tubs which either are newly constructed or have undergone modifications that impact the bonding or grounding system. No additional visual inspection shall be required for the issuance of an electrical certificate of compliance where a construction permit is issued for the electrical work pertaining to the pool, spa, or hot tub.
(b) The most recent bonding and grounding certificate and electrical certificate of compliance shall be posted in accordance with
As you can see there is no discription, definition or minimum requirements listed.
What you should do at a minimum is disconnect all grounds to pool devices such as lights and motors. Then take resistance reading between the grounds and then readings between all bonded parts. You disconnect the grounds so you can test bonding seperate from the ground paths. Record your findings and anything readings with a high resistance reading shoul be repaired. The state has no guidance as to what ohms reading would be acceptable so it is up to you.
