DESCRIPTION
The nVent RAYCHEM JBM-100-STB is a NEMA 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.
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.
The JBM-100-STB utilizes screw terminal blocks to make electrical
connections.
This kit may be installed at temperatures as low as –67°F (–55°C). For
easier installation store above freezing until just before installation.
For technical support call your local nVent representative.

NEMA 4X-rated connection kit Installation Instructions
2 | nVent.com/RAYCHEM
This component is an electrical device that must be installed correctly
to ensure proper operation and to prevent shock or fire. Read
these important warnings and carefully follow all of the installation
instructions.
• 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 nVent, agency certifications, and national
electrical codes, ground-fault equipment protection must be used.
Arcing may not be stopped by conventional circuit breakers.
• The power connection may be powered by more than one circuit. Be
sure all power sources are de-energized before opening box.
• Component approvals and performance are based on the use of nVent-
specified parts only. Do not use substitute parts or vinyl electrical tape.
• The black heating cable core and fibers are conductive and can short.
They must be properly insulated and kept dry.
• Damaged bus wires can overheat or short. Do not break bus wire
strands when scoring the jacket or core.
• Keep components and heating cable ends dry before and during
installation.
• Use only fire-resistant insulation materials, such as fiberglass wrap or
flame-retardant foam.
HEALTH HAZARD: Prolonged or repeated contact with the sealant
in the core sealer may cause skin irritation. Wash hands thoroughly.
Overheating or burning the sealant will produce fumes that may cause
polymer fume fever. Avoid contamination of cigarettes or tobacco.
Consult MSDS VEN 0058 for further information.

WARNING:
CAUTION:
Ce composant électrique doit être installé correctement pour éviter les
risques d'incendie ou de chocs électriques. Lire ces avertissements
importants et suivre attentivement toutes les instructions d'installation.
• Pour réduire le danger d'incendie causé par un arc électrique
entretenu, si le câble chauffant est endommagé ou mal installé,
et pour respecter les exigences de nVent et celles des codes
applicables, il est impératif d'utiliser une protection par disjoncteur
différentiel. Les disjoncteurs ordinaires ne sont pas toujours
capables de supprimer les arcs électriques.
• Les approbations et les performances des composants sont basées
sur l'utilisation des pièces nVent spécifiées seulement. N'utilisez pas
de pièces de rechange ou de ruban isolant en vinyle.
• Le noyau et les fibres du câble chauffant noir sont conducteurs et
peuvent provoquer un court-circuit. Ils doivent être correctement
isolés et gardés à sec.
• Les fils omnibus endommagés peuvent surchauffer ou subir un court-
circuit.
• Ne brisez jamais les fils omnibus lorsque vous incisez la gaine ou le
noyau.
• Maintenez les composants et les extrémités des câbles chauffants
secs avant et pendant l'installation.
• Les fils omnibus peuvent provoquer un court-circuit s'ils se touchent.
Les garder à l'écart les uns des autres
• N'utilisez que des matériaux isolants ininflammables, par exemple
une gaine de fibre de verre ou de la mousse ignifuge.
• Laissez ces instructions d'installation à l'utilisateur pour qu'il puisse
les consulter.
DANGER POUR LA SANTÉ: Le contact prolongé ou répété avec le
produit d'étanchéité du noyau peut provoquer une irritation de la peau.
Lavez-vous les mains soigneusement. La surchauffe et la combustion
du produit d'étanchéité produira des vapeurs qui peuvent causer la fièvre
des vapeurs de polymères. Évitez la contamination des cigarettes ou
du tabac. Consultez la fiche technique santé-sécurité (FTSS) VEN 0058
pour obtenir de plus amples informations.
