Where the Tesla JBS Junction Box is Used

Junction boxes are used wherever TPS (Twin and Earth) cables need to be joined, branched, or terminated in a location that is not at a switch, power point, or light fitting — in ceiling spaces, wall cavities, above suspended ceilings, and in protected concealed locations throughout a building. The Tesla JBS is the small junction box — its compact 70mm × 70mm × 37mm footprint makes it the practical choice for tight spaces, lightweight cable work, and installations where the smaller profile is preferred over the larger JBL.

Both the JBS and JBL include three single connectors and one double connector, covering the standard range of conductor connection requirements for single-phase TPS circuit joins. The single connectors suit joining two conductors. The double connector suits joining three conductors at a branch point — for example, where an active loops from one cable through the junction to a second cable.

The white polycarbonate housing is impact-resistant and suitable for use in typical concealed installation locations. The included connectors allow straightforward cable termination — insert conductors and tighten the screws to secure each connection without requiring crimping tools or tape.

Q: What connectors are included with the Tesla JBS junction box?
A: Three single connectors and one double connector are included — the same complement as the larger JBL. The single connectors join two conductors each; the double connector joins three conductors at a branch point.

Q: When should I use the JBS (small) instead of the JBL (large)?
A: Use the JBS where the installation space is restricted or where smaller cable sizes and fewer connections are involved — its 70mm × 70mm × 37mm footprint fits in tighter locations. Use the JBL (95mm × 65mm × 48mm) where larger cable sizes, more conductors, or additional working space inside the box is needed.

Q: Is the Tesla JBS suitable for outdoor use?
A: The JBS is designed for indoor use and protected concealed locations. For outdoor or weatherproof applications, an IP-rated enclosure is required — the JBS is not rated for direct weather exposure.
