A. Ground Fault Circuit Interrupter. It is a device intended for protection of personnel from electrical shock hazards.
A. Yes. It is used interchangeably.
A. If an approval agency like UL requires you to use a GFCI for your appliance. You can also use a GFCI for marketing purpose and to provide extra safety for your appliance.
A. It means that it will shut down the power to the appliance when there is a ground fault current at 6mA or more but not less than 4mA.
A. It is a problem in an electrical system or appliance that has an unintentional electrical connection between a part of the appliance operating normally at some potential to ground, and ground.
A. Ground fault can cause serious injury or even death if the personnel are exposed to it and the appliance has no GFCI protection.
A. Wall mount type, cord connected types (plug and in line), adapter type with built in receptacle(s), panel mount type, circuit breaker type, and custom made types.
A. We manufacture plug type(our popular model), in line, adapter, panel mount, exclusive custom designs for specific customers.
A. Yes. We can take a look and welcome your own design.
A. It is an insulation system of an appliance that has functional and supplementary insulation. You can tell if the appliance is rated double insulated by counting the number of conductors in the power cord. Double insulated appliance for outdoor use typically uses two conductor power cord.
A. The appliance designer and the electrical engineer will do the designing and approval agencies like UL does the testing if they can pass as double insulated and can use a two conductor power cord.
A. If your appliance cannot pass as double insulated, if the appliance maker wants to provide extra protection for marketing idea or approval agencies like UL requires 100% grounding in your appliance category.
A. Ground wire is usually green color, Hot or Line wire is black color and Return or Neutral wire is white color.
Q. Is it a problem if the power cord conductors are not connected to the correct terminal connections to your GFCI?
A. Yes, big problem and cause serious injury.
A. Yes. All our cord connected GFCI (plug and in line) are available to receive your 2 or 3 conductor power cord.
Q. Can I connect a two conductor power cord to your 3 prong GFCI and market it as grounded appliance and advertise it as extra safe?
A. No. That is cheating and approval agencies like UL will not allow it.
A. The GFCI will work right away when you plug it in the AC outlet. It will also work automatically when the electricity returns after shutdown.
A. The GFCI will not work right away when you plug it in the AC outlet. You need to press the reset button first to make it work. You have to press the reset button again after electricity shutdown.
A. We offer both types and the most popular type is auto reset because of the obvious benefits. It is a marketing, functional and safety decision on your part.
A. We offer manual and auto reset type with our patented electronic circuit. We also offer an economy manual reset version with a mechanical mechanism.
A. The housing is designed to pass the UL rain test requirement for outdoor use.
A. No. Our GFCI is not rated waterproof.
A. Yes. We have CSA and C UL US approvals.
A. In a GFCI, a pig tail refers to the input cord of an in line type GFCI.
A. According to UL, 12 inches is the maximum.
A. Yes. We have all the UL approvals and our cord connected GFCI are also Recognized Component by UL.
A. No. Only round cord and the most popular is SJTW. We can always tell you if your cord can be used or not by letting us know the cord specs.
A. It depends on your appliance rating. 14AWG is rated for 15A max, 16AWG is rated for 13A max and 18AWG is rated for 10A max.
Q. Why don’t you change the current rating marking on your GFCI when I only use 16AWG for 13A or 18AWG for 10A?
A. Our GFCI is still rated at 15A and we marked our GFCI with the corresponding load capacities using different AWG power cord.
A. No. It must be with “W” which means water resistant.
A. No. It is not required and our terminal box can accept some terminal types.
A. UL is making every GFCI manufacturer to change to 125V rating on the marking.
A. Our GFCI is marketed and available for use in the USA and Canada which is 60Hz. UL tested our GFCI and approved for 60Hz. We cannot guarantee that the GFCI will continue to work over long period of time at 50Hz.
A. Yes you can. ETL will allow UL approved devices to give you full approval.
A. It depends on your appliance’s electrical and temperature performance as evaluated by UL and other approval agencies.
A. If we supply you with the GFCI with cord, we must attach this warning label. Removing this label after we shipped and received by you will be your own responsibility.
A. Yes. Our GFCI fits most outdoor outlets than the competition.
A. It is a UL requirement on portable and cord connected GFCI. If the white wire or Neutral was cut or disconnected on the supply side of the GFCI, it must not provide power to the appliance.
A. Yes. Our patented circuit is designed with open neutral protection feature.
A. It is a requirement for all types of GFCI and if the white wire or Neutral becomes grounded on the appliance or load side, the GFCI will also cut power to the appliance.
A. No. We do not recommend using an extension cord.
A. No. A GFCI is not a circuit breaker and it is not designed to provide protection against short circuit.
Q. I thought GFCI will protect against shock hazard but your warning label say it will not protect against electric shock?
A. A GFCI only protects against electric shock if you get exposed to the black wire conductor directly or indirectly and you are grounded. If you are exposed and touched both black wire and white wire, you will get an electric shock. A GFCI will not protect you this way.
A. No. The GFCI will not cut power since you are not grounded and there is no shock hazard.
A. Our head office in USA works very closely with UL in Melville, New York and we never miss any standards and or file review so our GFCI meets all the latest requirements.
A. Yes. We test each GFCI according to the UL testing procedures.
A. We manufacture ALCI for hair dryers, heater fans, vacuum cleaners and other misc. applications; LCDI for cord protection for air conditioners, RCD for Australia and Europe and ELCI for equipment protection. Contact us for more details.
A. Call us and we will get back to you as soon as possible.
