What isALCI

An Appliance Leakage Current Interrupter (ALCI) is a safety device that detects ground faults and interrupts current flow automatically to prevent electrical shock. These devices are commonly used in electrical appliances like hair dryers, curling irons, and other electronic devices.

The ALCI includes a ground fault detection circuit and a trip mechanism that is automatically actuated in response to the presence of a ground fault. This means that if the device comes into contact with water or another conductive material, the ALCI will detect the ground fault and automatically shut off the current to prevent electrocution.

To ensure that the ALCI is functioning properly, a test button is provided that simulates a ground fault. The reset and test buttons are located on the ALCI housing, protected against unwanted tampering and accidental actuation by an integral protective barrier extending from the housing to form an enclosure in which the buttons are positioned.

It is important to note that these devices are UL Component Recognized and are not intended for general sale or use. They are intended for use as factory-mounted components of certain equipment where suitability of installation is determined by UL. They have not been evaluated for field installation and may or may not meet NEC requirements.

FAQs

What is the difference between an ALCI and a GFCI?

An ALCI and a GFCI are similar in that they both protect against electrical shocks. However, an ALCI is designed for use in appliances and electronic devices, while a GFCI is designed for use in outlets. A GFCI is required by the National Electrical Code (NEC) in certain areas of the home, such as the kitchen and bathroom.

Do I need an ALCI in my electrical appliances?

If your electrical appliance is designed to be used near water, such as a hair dryer or curling iron, it is a good idea to have an ALCI installed to protect against electrical shock. However, it’s important to note that an ALCI is not a substitute for a GFCI where required by the NEC.

Overall, an ALCI is an important safety device that can prevent electrical shocks and promote safe use of electrical appliances. If you are unsure whether your appliances have an ALCI installed, it’s important to consult with a licensed electrician.
