H908
WinterGard Plug-in Power Connection Kit
with End Seal
Description
The H908 is a plug-in, ground-fault-protected power connection kit for use
with WinterGard H311, H611, and H612 120-V heating cables.
This kit ensures compliance with Raychem and NEC requirements for
ground-fault protection of equipment. It does not protect people against the
hazards of electrical shock. The kit includes materials for one power
connection and end seal. All WinterGard heating cables are designed for
water-pipe freeze protection applications. Only the H612 heating cable can be
used for both pipe freeze protection and roof and gutter de-icing applications.
For additional technical support call Raychem at 800-542-8936.

LISTED
These components are electrical devices. They must be
installed correctly to ensure proper operation and to
prevent shock or fire. Carefully follow all of the installa-
tion instructions and read these important warnings.
• To minimize the danger of fire from sustained
electrical arcing if the heating cable is damaged or
improperly installed, and to comply with the
requirements of Raychem and the 1996 National
Electrical Code, ground-fault equipment protection
must be used on each heating cable branch circuit.
Arcing may not be stopped by conventional circuit
protection.
• Component approvals and performance are based
on the use of specified parts only. Do not substitute
parts or use vinyl electrical tape.
• The black heating-cable core is conductive and can
short. It must be properly insulated and kept dry.
• Keep components and heating cable ends dry
before and during installation.
• Damaged bus wires can overheat or short. Do not
break braid or bus wire strands when scoring the
jacket or core.
• Bus wires will short if they contact each other.
Keep bus wires separated.
• Heat-damaged components can short. Use a heat
gun or a torch with a soft, yellow, low-heat flame,
not a blue focused flame. Keep the flame moving to
avoid overheating, blistering, or charring the heat-
shrinkable tubes. Avoid heating other components.
Replace any damaged parts.
• Use only fire-resistant insulation materials such as
fiberglass wrap.
• Leave these installation instructions with the user
for future reference.
Charring or burning the heat-shrinkable tubes
in this kit will produce fumes that may cause eye,
skin, nose, and throat irritation. Consult Material
Safety Data Sheet RAY/3122.
