The Conductor hub was developed inline with the requirements for AS/NZS3000 equipotential bonding guidelines. It is a bonding connection point that is compatible with the Wiring Rules update (AS/NZS3000:2018) and can be used in both swimming pool and spa areas as well as domestic and commercial construction that has a shower or bath on a slab containing reinforced steel.

Equipotential bonding is the act of bonding all the metal components in an area together to create substantially the same electrical potential, so that, under fault conditions, the difference in potential between simultaneously accessible exposed and extraneous conductive parts will not cause electric shock.
Australian Standard AS/NZS3000:2018 Section 184.108.40.206 & 220.127.116.11 outline the requirements for equipotential bonding in a swimming pool/spa area as well as in domestic and commercial construction in a room containing a shower or bath.
Projects that are constructed in Australia or New Zealand that require equipotential bonding under the Wiring Rules shall, in a swimming pool / spa environment form an equipotential bond between all fixed conductive material within arm’s reach (1.25m) of the pool or spa’s edge that has a surface area larger than 100mm. This includes items like; the reinforcing steel shell of the pool or spa, the steel within the deck or under tiling, metal pool fencing or spigots, any metal lights, windows, downpipes, ladders etc. Under the rules the bonding connection point shall be located in an area that is testable and accessible and have space for further connections after the construction has been complete (Section 18.104.22.168.4)
In a domestic or commercial environment, this would include the re-enforcing steel in the concrete slab or wall.
The Conductor Hub unit is 160mm in diameter. This enables contractors to fit their hand inside the base to work on the bus bar.
Yes the Conductor hub base has been designed to be height adjustable and can suit multiple tile thicknesses. The base comes standard at a height of 150mm but can be cut down as low as 100mm to fit a standard concrete slab.
The unit needs to be installed prior to the concrete pour. It attaches to the reinforcing steel.
The bar is 1 metre long to enable four connection points between the conductive bar and the reinforcing steel, ensuring a secure bond has been formed. As the Conductor Hub is a multi use product for swimming pools, domestic and commercial wet area applications, the bar can be cut down if required to suit the installation environment.
The standard kit comes with a Conductor Hub base, 1m copper bar (pre drilled), a brass busbar and 2 stainless steel screws, 4 extra conduit connectors, 5 stainless steel zip ties, a lid assembly in Light Grey which includes a collar and o-ring, installation compliance card, installation sticker, instruction manual.
5/16 drill hex bit, 20mm hole saw (if adding extra conduit connection points), 20mm conduit, silicone.

Yes you can purchase a different coloured lid here to suit your tiles or deck. They come in Dark Grey, White, Brown and Beige.
It isn’t necessary for the lid of the Conductor Hub to be seen after the construction is complete. You can cover the lid with a stone or tile that can be removed if required. You need to ensure however that the location of the Conductor Hub is marked in the meter box with the provided compliance sticker as per the Australian Standard requirements.
No, the Conductor Hub has been designed so it can be installed in multiple locations and directions to suit the pool’s design. If the Reinforcing steel is continuous (ie. has starter bars from the pool shell or bond beam into the external slab) the Conductor hub can be installed anywhere in the surrounding steel/slab. The Hub can also be installed in the pool coping if desired or on a horizontal external surface of the external pool wall if there is an exposed section that is accessible post construction.
The Conductor Hub can be located in a cupboard or under the washing machine in a laundry so long as the reinforcing steel is continuous to the wet area.
The Conductor Hub would be located in the power distribution room on each level so long as the reinforcing steel is continuous to wet areas.
