Innovative Pool Products GFX-220 GFCI
GFX-220 is a new type of 20 amp 240 volt feed through Ground Fault
Circuit Interrupter (GFCI) specifically designed to withstand the high
frequency noise and spikes caused by Variable Speed Pumps, LED lighting and
transformers. The GFX-220 functions very well with all brands of
Variable Speed Pumps and other swimming pool equipment, meeting all National
Electric Code requirements.
The GFX-220 is not a circuit breaker, but a feed through Ground Fault Circuit Interrupter. A properly sized 15 or 20 amp 2 pole circuit breaker is needed to supply power to the GFX-220. Since it is not a circuit breaker you may use any brand of 2 pole circuit breaker to feed the GFX-220. This allows the use of branch circuits at the pool equipment or the use of the GFX-220 on projects that do not have a load center at the equipment location. Because you can now use ½ size or Quad style circuit breakers you may use smaller load centers for multi pump projects allowing for even greater savings.
For Your Electrician
Important: The GFX-220 does not include a neutral conductor connection. You cannot use the GFX-220 to protect any 120v devices. If you have 120 volt equipment that needs to be on the 240 volt circuit you must attach a separate 120 volt GFCI to the line side of the GFX-220. Usually the manufacturers of Chlorinators, Ozone Generators and U.V. Purifiers have the ability to run on 240 volts.
The GFX-220 uses Weather Resistant internal components. The GFX-220 must be mounted in a NEMA 3R weatherproof enclosure when used in wet locations. There is not a receptacle on the GFX-220 so a Weatherproof While in Use cover is not needed, a standard weatherproof cover is sufficient.
Please use the manufacturers’ instructions on sealing hubs and conduit entries into the weatherproof enclosure. Most weatherproof boxes are listed as weatherproof when the hubs are sealed with silicone. This is a good practice and will help to keep water out of the box.
Many panel manufacturers have a location inside their enclosures that is suitable for the GFX-220. In these cases there is no need for an additional weatherproof box and cover.
