DESCRIPTION

The nVent RAYCHEM JBM-100-L-A is a Type 4X-rated connection kit. It is

designed for use with nVent RAYCHEM BTV-CR, BTV-CT, QTVR-CT, XTV-CT,

KTV-CT, HTV-CT and VPL-CT industrial parallel heating cables. The kit can be

used to connect one, two, or three heating cables to power, to connect two

separate heat-trace circuits, or to splice or tee up to three heating cables. The

kit includes a plug-in light module that indicates when power is supplied to the

heating cable circuit.

Note: For two or more heating cables powered by a single circuit, the length of

each heating cable should not exceed the maximum allowable circuit length

published in the nVent RAYCHEM self-regulating cables design guide and the

total current of all heating cables on the circuit should equal no more than 80%

of the circuit breaker current rating.

This kit may be installed at temperatures as low as –40°F (–40°C). For easier

installation store above freezing until just before installation.

1A 1B VPL BTV, QTVR, XTV, KTV, HTV • Cut each heating cable 12 in (30 cm) from the center of the first indentation, cut at a 45° angle. Cut at 45 angle 12 in (30 cm) minimum 24 in (60 cm) Indentation (bus wire connection) • After heating cable has been cut, align indentations. Allow approximately 24 in (60 cm) of heating cable for installation. Centerline of connection • Allow approximately 24 in (60 cm) of heating cable for installation.

11 12 • Slide strain relief over heating cables, down onto box nut. • Secure strain relief by tightening screws. CAUTION: Health Hazard. Wash hands after contact with sealant. Consult material safety data sheet VEN 0058. Avertissement: risque pour la santé. Se laver les mains après tout contact avec le produit d’étanchéité. Consulter la fiche de données de sécurité VEN 0058. • If needed, re-twist and straighten bus wires, then insert bus wires into guide tubes as shown.

17 This kit uses spring clamp style terminals. Terminals use a steel spring to clamp the wire to provide improved vibration resistance, reduced maintenance and faster installation. To connect wires, firmly insert a slotted screwdriver into the square hole ( 1 ) to open the spring. When fully inserted, the screwdriver will lock into place, allowing you to remove your hand and insert the wire into the round hole ( 2 ). Remove the screwdriver to clamp the wire.
