Why the MB/WP Is the Right Mounting Block for Outdoor Conduit Installations

The MB/WP differs from the standard MB universal mounting block in one critical way — it has conduit entry knockouts built in. The side entries (2 x 20mm, open) and rear entries (2 x 20mm, pre-cut) allow conduit to be connected directly into the back and sides of the block, routing cable through the conduit run and up into the GPO or switch plate above without exposing the cable. This is the correct installation method for surface-mounted outdoor electrical work in Australia where conduit wiring is used — the MB/WP is the mounting block that supports that method properly.

The solid backing on the MB/WP provides an enclosed base beneath the plate, protecting the wiring connections from weather and moisture ingress from behind. Combined with a weatherproof-rated plate such as the Transco Neptune P2WP or similar, the MB/WP provides a complete surface mount solution for outdoor conduit installations. The white polycarbonate construction is durable and UV-stable, suitable for long-term outdoor exposure without degrading or discolouring.

The W76 x L119mm footprint and 84mm fixing centres align with all standard Australian GPO and switch plates, making the MB/WP a universal fit across plate brands and series. Both horizontal and vertical mounting positions are supported. Sold individually — specify the quantity needed for the installation and pair with the appropriate weatherproof-rated plate for the application.

Q: What is the difference between the MB/WP and the standard MB mounting block?
A: The MB/WP has conduit entry knockouts (2 x 20mm side entries and 2 x 20mm rear entries) specifically for outdoor conduit wiring installations. The standard MB is a solid block without conduit entries, suited to surface mounting where cable enters through the back of the wall rather than through conduit. The MB/WP is the correct choice for surface-mounted outdoor installations where conduit wiring is used.

Q: What conduit size does the Transco MB/WP accept?
A: The MB/WP has 20mm conduit entries — 2 x 20mm open entries on the side and 2 x 20mm pre-cut entries on the rear. These suit standard 20mm electrical conduit fittings used in Australian surface-mounted outdoor wiring installations.

Q: Can the Transco MB/WP be mounted both horizontally and vertically?
A: Yes. The MB/WP supports both horizontal and vertical mounting positions, giving full flexibility to suit the orientation of the wall plate being installed.
