FAQ

The selection of proper EnFin unit(s) depends on various parameters, such as the voltage configuration and panel amperage. If your installation is somewhere outside the United States, or you are looking at a commercial or industrial installation, please send us a message so we can address your individual needs/requirements. Some units have many variations. We want you to be satisfied with any unit we provide. Units are available for most countries around the world.

Yes, EnFin units will protect your facility/residence if the surge is passing through the main panel. However, surges can enter the facility/residence in many ways: through the ground, power-lines, communication cables, and more. The surge takes the path of least resistance to the load. If the origin or source of the surge is not passing through the main panel, the EnFin unit at the main panel may not protect your entire facility/residence effectively. For this reason, individual EnFin units at the sub-panel, or the load centers, are recommended, such as EnFin power supplies.

Maybe! EnFin units are designed to remove the electrical noise in the system, which is often wasted energy. Removing the noise may result in energy savings for the facility/residence. However, EnFin will not make any claims on the amount of energy savings that can be achieved in a facility.

Depending on the application, EnFin units come in many sizes. The smallest OEM fits in a T5/T8 lighting fixture, and the largest EFC2888 series (24 x 24 x 12 in) can be conveniently mounted at the main panel.

We recommend installing a larger EnFin unit in the main panel, and a smaller EnFin unit at the sub-panel to protect both panels.

The EFC2800 series comes with a 10-year standard warranty, and the rest of EnFin units come with a 5-year warranty.

The installation has to be performed by a certified and licensed electrician. Please read the installation manual before installing the product.

Single-phase is 2 Line, neutral and ground. Ex: US residential panel with 120/240v. Single leg is One Line, neutral and ground. Ex: Asian residential panel with 240V L-L.

The warranty form has to be submitted within the first 30 days of the purchase. The warranty form is available online for your convenience.

The visible LEDs indicate the active phase of the units.

Depending on the noise levels in the system, EnFin units can get as hot as 140F (60C) on the surface.

Yes, EnFin units can be installed on the side, bottom, or top-mounted to the cabinet.

Check with your local electrical codes to install power quality equipment inside the panel. EnFin units are installed inside the panel in various countries.

Yes, with the help of external casing. EnFin units are not water-proof and are required to be inside NEMA-rated casings if they are installed outside of the building/residence/facility.
