A. Appliance Leakage Circuit Interrupter. It is a device intended for protection of personnel from electrical shock hazards.
A. If an approval agency like UL requires you to use an ALCI for your appliance. You can also use an ALCI for marketing purpose if UL will allow it and to provide extra safety for your appliance.
A. It will shut down the power to the appliance when there is a ground fault current of 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 ALCI or GFCI protection.
A. Cord connected types (plug and in line), panel mount and custom made types.
A. We manufacture plug type(our popular model), in line, 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 cords.
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 ALCI?
A. Yes, big problem and cause serious injury.
A. Yes. All our cord connected ALCI (plug and in line) are available to receive your 2 conductor power cord and some models can accept 3 conductor power cord.
Q. Can I connect a two conductor power cord to your 3 prong ALCI and market it as grounded appliance and advertise it as extra safe?
A. No. This is not acceptable and approval agencies like UL will not allow it.
A. The ALCI will work right away when you plug it in the AC outlet as long as the reset button is pushed on. It will stay on when the AC power is lost and returns after shutdown.
A. It depends on your appliance requirement to secure safety agency approval like UL, ETL, etc. Hair dryer is one example of an appliance requiring an ALCI, bathroom heater fans, wet/dry vacuum cleaner, carpet cleaner, hair blower, etc.
A. ALCI is a UL Recognized Component and marked “UR”. It is not UL listed which uses a label.
A. 99.9% of ALCI applications are mostly indoor use therefore, there is no rainproof requirement.
A. Yes but we do not make rainproof ALCI. Besides, UL requires a GFCI for most outdoor applications.
A. There is no requirement for ALCI in Canada.
A. In an ALCI, a pig tail refers to the input cord of an in line type ALCI.
A. According to UL, 12 inches is the maximum.
A. Yes. We have some models we can ship with no cords. Contact us for details.
A. Yes. We have some models that can use round cords and the most popular is SVT. 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. 15AWG is rated for 15A max, 16AWG is rated for 13A max and 18AWG is rated for 10A max.
A. Immersion Detection Circuit Interrupter. It is a device intended for protection of personnel from electrical shock hazards.
A. No. We believe no one in the industry makes this device anymore because the overall cost is greater than an ALCI.
A. An IDCI is a lot simpler than an ALCI but it requires a special power cord with a 3rd sensing conductor and must be connected inside the appliance to function properly.
A. No. It is not required and our terminal box (solder or screw terminal) can accept some terminal types.
A. Our ALCI is marketed and available for use in the USA which is 60Hz. UL tested our ALCI and approved for 60Hz. We cannot guarantee that the ALCI 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 ALCI with cord and your application requires a warning label, we must attach this warning label. Removing this label after we shipped and received by you will be your own responsibility.
A. It is a UL requirement on portable and cord connected GFCI only. 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. It is a requirement for all types of GFCI only 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. An ALCI is not a circuit breaker and it is not designed to provide protection against short circuit.
Q. I thought ALCI will protect against shock hazard but I read somewhere it will not protect against electric shock?
A. An ALCI or 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. An ALCI or GFCI will not protect you this way.
A. No. The ALCI 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 ALCI meets all the latest requirements.
A. Yes. We test each ALCI according to the UL testing procedures.
A. We manufacture GFCI for many outdoor applications, power washer, extension cords, 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.
