Boards & Units

YES! Our consumer units are designed with the installer in mind. They feature round knockouts for easy installation of round cable glands, conduits, cable grommets, and for terminating SWA final circuit cables with complete flexibility.

Please find your nearest stockists and wholesaler branches in "WHERE TO BUY?" section.

Yes, our consumer units are designed to be fully interchangeable, allowing for both switched and unswitched neutral pole RCBO options. This versatility ensures compatibility with a variety of electrical setups.

The E-TPN-04/08/12/16LW range is set up for 10Ka fault current MCB/RCBO devices. The breaker you have may be a 6Ka domestic type so a conversion kit can be brought separately E-TPNZB04/08/12/16. The fault current for the installation must be known before fitting domestic breakers. Please note that we do not offer 3 pole MCB’s in 6Ka so if a 3 phase breaker is required the whole board must be kept as 10Ka.

No but a 3 pole MCB can be fitted in the TPN board then a 4 pole RCD can be fitted into the TPN-EXT19 above or below the board to give the same level of protection.

The original LEB breakers are now obsolete but we do have some old stock still available, please call our sales team for current availability. Our current E10 range is not a replacement. Try “B” and “D” curve instead of “C” if suitable for the application. If a single pole MCB is required then our G06 range will fit but are only 6Ka rated while the LEB’s are 10Ka. The fault current of the system should be measured to see if suitable before fitting.

No but please call our technical team to discuss your matter and we will endeavour to do their best to help out.

Yes our domestic RCBO’s (RCBO-16/30/SP) are compatible with the LEB breakers but are only 6Ka rated while the LEB’s are 10Ka. The fault current of the system should be measured to see if suitable before fitting.

Yes our dual RCCB/split load boards are all supplied with this link which can supply 2 modules next to the main switch. The high integrity link is for critical circuits such as smoke alarms, burglar alarms and also surge protectors so they operate regardless of the RCCB’s being on or off.

No this board is only to be used as an accessory to our TPN boards for fitting a surge device, time clocks, contactors and RCD’s. It does not contain an earth/neutral bar or a top plate as these are done in the TPN board.

We do not specifically offer spreader boxes but if you use the same size enclosure from our WME enclosure range then it can be turned upside down then both gland plates can be removed so the large cable can go through this opening. The door on the extra box can be swapped around so it hinges from the same side.
