Final answer:
The minimum size of bonding conductor for bonding the metal parts of non-electrical equipment for in-ground swimming pools is determined by the National Electrical Code (NEC) in the United States. It must have a minimum size of 8 AWG copper or 6 AWG aluminum. Local electrical codes may have different requirements.
Step-by-step explanation:
The minimum size of bonding conductor for bonding the metal parts of non-electrical equipment for in-ground swimming pools is determined by the National Electrical Code (NEC) in the United States. According to NEC Article 680, the bonding conductor must have a minimum size of 8 AWG copper or 6 AWG aluminum. This ensures proper grounding and can help prevent electrical shock hazards.
For example, if you have a metal ladder or handrail in the pool area that needs to be bonded, you would use a minimum of 8 AWG copper conductor for proper bonding.
It's important to check the specific requirements of your local electrical codes as they may have different regulations for bonding in-ground pool equipment.
