C A HEATING CABLE GLAND KIT INSTALLATION INSTRUCTIONS

Transcription

1 C A HEATING CABLE GLAND KIT INSTALLATION INSTRUCTIONS DESCRIPTION The C A is a NEMA 4X-rated gland kit used to transition heating cables into a junction box when making connections off of a pipe, tank or roof. It may be used for power, splice, or tee connections. The C A is for use with Raychem BTV-CR, BTV-CT, QTVR-CT, XTV-CT, KTV-CT(1), LBTV2-CT(2), VPL-CT industrial parallel heating cables and GM-X and GM-XT roof and gutter de-icing heating cables. The kit does not include the junction box, flexible tubing, or tape, which are required to make a complete connection.
