Description

Rylec JB320C. 20mm 3 Way Shallow Conduit Junction Box. PVC Grey. Round.

The Rylec JB320C is a 20mm three way shallow PVC junction box for use with 20mm corrugated or rigid electrical conduit systems. Three conduit entries — the T-junction configuration where one conduit arrives and two continue, or where three conduits meet at a branch point. Round shape, grey PVC, shallow profile for surface mounted conduit installations. Sold individually.

Where the Rylec JB320C 3 Way Junction Box is Used

The JB320C is the 20mm three way shallow junction box — the T-junction box used wherever a 20mm conduit run branches into two directions from a single incoming conduit, or where three conduit runs meet at one point. In surface-mounted conduit installations, T-junctions occur whenever a circuit needs to branch — for example where a main conduit run along a wall needs to supply both a socket on the left and a socket on the right, or where a conduit run from a switchboard branches to serve two different directions through a building.

The three conduit entry positions on the round junction box body allow the three conduit entries to be positioned in different orientations relative to the mounting surface — the exact arrangement will depend on which entry faces are used for the incoming and outgoing conduits and how the box is oriented during installation. The shallow profile keeps the box protrusion consistent with the rest of the surface-mounted conduit system.

The Rylec JB range for 20mm conduit covers 1 way (JB120C), 2 way straight (JB220C), 2 way right angle (JB2090C), 3 way (JB320C — this product), and 4 way (JB420C) — all grey PVC, shallow profile. The 25mm equivalent is JB325C.

Q: What does "3 way" mean on the JB320C?
A: "3 way" means the box has three conduit entry points — configured as a T-junction where one conduit arrives and two continue, or where three conduits meet at one point. For two-conduit junctions use JB220C (straight) or JB2090C (right angle); for four-conduit cross junctions use JB420C.

Q: What conduit size does the JB320C suit?
A: The JB320C suits 20mm corrugated flexible conduit and 20mm rigid PVC conduit.

Q: Is there a 25mm version of the 3 way shallow junction box?
A: Yes — the JB325C is the 25mm 3 way shallow junction box, for installations using 25mm conduit.
