Outdoor Snow Melting Junction Box - Large - In-Ground

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.

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).

Minimum is 1.5“ and Maximum is 2.5“

Small In-Ground Snow Melting Junction Box can accommodate 1 or 2 cold leads, while a Large In-Ground Box can accommodate between 3 to 8 cold leads. A large Wall-Mounted Junction Box can accommodate up to 8 cold leads.

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.

This feature prevents the snow melting system from running, by default, in temperatures below 17°F (–8.33°C), or as set by the user. At temperatures this low, it becomes difficult for the system to effectively melt the snow. It is, however, possible to turn off this feature should the system be required to keep running during these low temperatures.

The best home features for cold climates include a simple gable roof to shed snow, covered entrances for protection, airtight triple-pane windows to prevent heat loss, and radiant heating systems. These features work together to maintain interior warmth, reduce energy bills by up to 25%, and ensure structural safety during harsh winters.
