Small Relay Panel, (2x) 2-Pole (RLY-4PL-CC)

GFEP is the National Electric Code (NEC) required protection for fixed outdoor deicing and snow-melting equipment, which may be accomplished by using circuit breakers equipped with ground-fault equipment protection (GFEP) of 30 mA. It is important to understand that this required equipment protection is NOT the same as a 5 mA GFCI used for personal protection.

When the design requirement's amp draw exceeds the selected controller's capacity.

The most common spacing for snow melting systems is 3“ from wire to wire. However, we can design snow melting systems based on your local climate and weather expectations that might have different cable spacings to ensure the most efficient system possible. We also offer snow melting mats with 3" and 4" spacing.

In an area free of obstruction and able to detect rain or snow, yet low enough so that it is easily accessible if service is needed. Atop a fence post or on an 'L' bracket on the side of a building are common.

A GFCI/GFEP (Ground Fault Circuit Interrupter / Ground Fault Equipment Protection) works differently than a circuit breaker by specifically detecting a small imbalance in electrical current between the hot and neutral wires, which indicates a potential ground fault (like a person touching a live wire), and instantly shutting off the power to prevent shock, while a circuit breaker only trips when there's a significant overload in current flow on the circuit, like a short circuit or too many appliances plugged in.

The electrician must route the cold lead(s) through rigid metal conduit(s) or other approved means, to get back to an accessible weatherproof junction box(s). Care must be taken by the electrician so that none of the heated section of Cable enters the conduit(s).

Relays can fail due to excessive current or voltage. When a relay is exposed to too much current, the contacts can burn out. High voltage can also damage the coil. Other reasons include mechanical wear and tear, dust or dirt buildup, and moisture. These factors can cause the relay to malfunction or stop working entirely. Regular maintenance and using the relay within its specified limits can help prevent failures.

Minimum is 1.5“ and Maximum is 2.5“

Ground fault equipment protection (GFEP) is intended to provide protection for equipment against damaging line-to-ground currents by disconnecting all ungrounded conductors of the faulted circuit.

A 2 pole single-phase 240V circuit works by continuously monitoring the current flowing through both hot wires of the circuit. If it detects even a slight imbalance between the current on each hot wire (indicating a ground fault), it will quickly trip, cutting off power to the circuit. Essentially, it compares each leg of the 240V circuit and trips if they are not precisely equal.
