NEC (National electric code) .... "GFCI
protection
is
required for all receptacles
(outlets) that supply power above the low-voltage
contact limit (120 volt) to equipment that handles pool water. This
requirement is
in addition to the GFCI protection required for 120V-240V,
single-phase pool
pump motors." This means all outdoor outlets, including outlets used in and around swimming pools, and located inside Intermatic control panels must be GFCI protected. This can be accomplished b  y installing
single-pole GFCI breaker inside the Intermatic control center, or by
using GFCI outlets. It also means all 120-240 volt pumps, motors etc used for pool equipment must be GFCI protected. Both the 240 volt pump and 120 volt outlets etc can be protected all-in-one by installing a 240 volt GFCI circuit breaker inside the main breaker box ... then running 120-240 volt 3 wire cable from main breaker breaker box to control panel.  Caution:
Only 1 GFCI per circuit. So if main breaker panel has a GFCI breaker,
then
another GFCI on same circuit will cause frequent tripping and
malfunctions.Due
to complexity of
GFCI, a monthly test is required: press test and reset buttons. If GFCI
resets, then it is functioning. Safest practice is test each time
before use. Only 1 GFCI per circuit. GFCI must be grounded. Improper grounding will cause delay in GFCI response. Using 2-prong cord instead of 3-prong grounded cord means GFCI will not react instantly. The delay can cause shock and hazard, but typically not death. Exceptions exist. |

Match
wire size and breaker amp rating If your home was wired by professional electrician who pulled permits, then circuit breaker and wire size will match. If manufactured home or travel trailer has not been altered by homeowner then breaker and wire size will match. Safe maximum of amp draw on a breaker is 80% rated value of breaker. Look at label on each load (TV, refrigerator, box fan etc). Add up total watt load on circuit. Divide the watts by the voltage on line = amps. If breaker is oversized for wire... fire danger Breaker can let the voltage push too much amperage (current of electrons) through the matrix (atomic structure) of the wire. The natural resistance of the copper wire creates a 'friction' that overheats the wire and causes fire. Call electrician if you suspect wiring is not correct, Main breaker terminals are still Hot when main breaker is turned off. Absolute electrocution danger when removing cover off main panel. More information below. Use 600 volt solid copper wire only Do not use stranded wire inside main breaker box or any permanent box. Stranded wire can be used for connectors and plugs, but comes loose under screw terminals of breaker, switch, outlet, or timer etc when heat on wire causes expansion and contraction of wire. Do not use extension cord for permanent household wiring Extension cords are used for connectors and plugs only.

Circuit
breaker and wire size must match Chart on left shows that 30 amp breaker matches 10 gauge copper wire. Do not use aluminum wire. Copper wire is safe. All wire expands when electricity travels through wire. Aluminum wire expands more than copper wire. Expansion causes connection points to come loose resulting in fire hazard. Special compression fittings and CO-AL rated devices must be used with aluminum wire.

If you have
240 volt ... but not 120 volt at
control panel... then 3 options: 1) Bring in a Neutral wire from main breaker box. All subsequent 120 volt circuits at control panel will use a Hot from main breaker box, and the new Neutral from main box. The 120 volt circuits that are made from this will be protected by the 240 volt GFCI that is installed in control panel or main breaker box. 2) Select indoor outlet located on other side of wall from control panel, drill through wall and bring separate 120 volt line to control panel. If the 120 volt circuits used for the pool area are powered by the Hot and Neutral from this new line, then a GFCI must be added to the 120 volt circuit, either at the control panel or convert the indoor outlet to a GFCI or install GFCI breaker inside main breaker box. 3) Install 120-240 volt power transformer inside another enclosure, and create 120 volt from the 240 volt line.

GFCI circuit breakers Single pole and double pole GFCI is same as ordinary breaker, and will trip when amperage or heat on the wire exceeds amp rating of breaker. However, heat on the wire will NOT trip breaker immediately, and cannot protect people from electrocution. The GFCI protects from electrocution by immediately tripping when number of electrons flowing on one wire is different from electrons flowing on the other wire. White wire must connect to Neutral busbar. Avoid double GFCI protection on same circuit. Unlike breakers and fuses that can be added at any point along same wire, multiple GFCI or AFCI on same wire can cause tripping. This means, if the circuit breaker that supplies power to the Intermatic control center is a GFCI or AFCI, then do not add GFCI or AFCI in the control center.
