5. Has an on/off switch that has an indicator light (pilot light).
The indicator light
should be wired to light up when your cable is powered (see
Figure 1
). This will
help you minimize energy consumption and help ensure the cable is not powered
in warm weather. Turning on the cable in warm weather can cause it to overheat
and may increase the risk of fire or electric shock.
6. Is protected from the weather.
The connection between the plug and receptacle
must be protected from rain, snow or other elements. You may use either:
• a receptacle in a location that is protected from the elements. Sometimes an
eave can provide adequate protection.
• a receptacle that has a weatherproof enclosure, similar to that shown below.
This type of enclosure is sometimes called an “in-use receptacle cover.”
7. Is within 6 ft (1.82 m) of the cable starting point on the roof.
(See
Planning on
page 8
.) The cable’s power cord is 6 ft (1.82 m) long, and the remainder of the
cable is heated.
8.
Choosing a receptacle that is within 6 ft (1.82 m) of the start point will ensure that
the heated portion of the cable is entirely on the roof. This will also avoid contact
by persons or equipment (such as yard tools) that can move or damage the cable.
9.
The use of a properly located receptacle will also eliminate the need for an exten-
sion cord. °STELPRO recommends you not use an extension cord with this cable,
as this may increase the risk of fire or electric shock.
10.
Remember, there may be different or additional requirements related to local or
national codes and ordinances. Check with your local electrical inspector or a
licensed electrician if you are unsure about these codes and ordinances.
