Where the Rylec JB220C Junction Box is Used

The JB220C is the 20mm two way shallow conduit junction box — the inline version that allows a conduit run to be accessed at a mid-point, or provides a simple branch where one conduit arrives and one continues in the same or opposite direction. Two way junction boxes are the most common type used in surface-mounted conduit installations for residential and light commercial electrical work, providing accessible cable join points at regular intervals along a conduit run or at changes in cable route direction.

The 20mm size is the most common conduit size used in Australian residential and light commercial electrical installations — the JB220C suits the standard 20mm corrugated flexible conduit and 20mm rigid PVC conduit used to protect TPS cable runs along walls, ceilings, and exposed surfaces. The shallow profile keeps the junction box's protrusion from the mounting surface to a minimum — matching the low profile of the conduit saddles and fittings used in a surface-mounted conduit installation.

The Rylec JB range for 20mm conduit covers 1 way (JB120C), 2 way (JB220C — this product), 3 way (JB320C), and 4 way (JB420C) — all grey PVC, all shallow profile. The same range is available in 25mm conduit size (JB125C through JB425C). Choose the correct number of ways for the number of conduits meeting at each junction point.

Q: What does "2 way" mean on the JB220C?
A: "2 way" means the box has two conduit entry points. A 2 way junction box is used inline along a conduit run — one conduit enters from one side and one continues from the other — or at any point where exactly two conduits need to connect at the same junction box. For junction points where 3 or 4 conduits meet, use the JB320C (3 way) or JB420C (4 way).

Q: What conduit size does the JB220C suit?
A: The JB220C suits 20mm conduit — both 20mm corrugated flexible conduit and 20mm rigid PVC conduit.

Q: What is the difference between JB220C (20mm) and JB225C (25mm)?
A: Both are 2 way shallow junction boxes — the JB220C suits 20mm conduit and the JB225C suits 25mm conduit. Choose based on the conduit size used in the installation.
