Bonding

The National Electrical Code (NEC in the United
® ®
States) or the Canadian Electrical Code (CEC in Canada)
requires metal parts of electrical equipment associated
with the pool water circulation and fixed metal parts
within 5 ft of the pool wall in the USA, 10 ft for
Canada, to be bonded to each other. Check your local
codes to determine if the NEC or CEC and/or other
local installation codes are enforced by the Authority
Having Jurisdiction (AHJ in the United States) or the
local competent authorities in Canada. A solid copper
8.37mm (8 AWG) wire is required, per the NEC and
2
CEC (CEC requirement is 6 AWG), with the bonding
must be accomplished by using a solid copper conductor,
No. 8 AWG or larger. In Canada, No. 6 AWG or larger
must be used. The TruDose Chemical Controller does
not have any exposed metal parts requiring equipotential
bonding, nor metal parts in contact with the water
circulation system, and therefore does not require
equipotential bonding connections.
National Electrical Code (NEC ) requires bonding
® ®
of the Pool Water. Where none of the bonded pool
equipment, structures, or parts are in direct connection
with the pool water; the pool water shall be in direct
contact with an approved corrosion-resistant conductive
surface that exposes not less than 5800 mm² (9 in²) of the
surface area to the pool water at all times. The conductive
surface shall be located where it is not exposed to
physical damage or dislodgement during usual pool
activities, and it shall be bonded in accordance with
the bonding requirements of NEC Article 680. Refer
to locally enforced codes for any additional bonding
requirements.
