This 20mm PVC junction box 1 way is a round white end box with a single 20mm entry on the side, for the end of a conduit run. The round lid fixes with 2 screws. If the conduit carries on past the box, use the 2 way junction box for a straight run, or the 3 way tee junction box where a branch goes off at 90 degrees.
Where a 1 way PVC junction box goes
Use it where a 20mm conduit run stops: at an outside light, a camera, an alarm sensor or a light point on a wall. The cable comes along the conduit, in through the side entry, and the connection is made inside the box.
Fitting the conduit
The side entry takes 20mm PVC conduit. Push the conduit into the entry, or glue it with PVC solvent cement for a firmer joint. Join lengths of conduit along the way with a 20mm coupling.
The lid
The round lid sits on top and fixes with 2 screws, so you can open it again later to check or change the connection.
Where the conduit carries mains wiring, the work must be done by a registered electrician who issues a Certificate of Compliance (CoC). Alectra Solutions supplies the fittings only and does not install.
