Hager Guidance
This guidance must be read in conjunction
with the BEAMA attached technical bulletin:
RCBO Single Pole RCBO 6kA 30mA
RCBO application
Connection of Unidirectional and Bidirectional Residual Current Devices
(RCDs) and Miniature Circuit-Breakers (MCBs) to power supplies e.g. battery
storage, Photovoltaic (PV) systems, Electric Vehicles (EV) to home, a micro-
generator, or grid (mains) supply.
The electrical inspector/electrical installation duty holder is responsible
for making the decision on any required action and related time scales. Hager
suggests that based on the potential safety issues raised in the BEAMA
bulletin, it would appear that any incorrectly selected and installed RCBOs
should be replaced with a suitable device.
The following information will assist in identifying any Hager RCBO that has been selected and installed incorrectly, together with the appropriate solution.
Issue:
-
RCBOs that do not switch the neutral as required by BS 7671 Regulation 551.7.1.
A solid neutral is indicated in instructions or a diagram on the RCBO. -
Unidirectional RCBOs with their outgoing/ load terminals connected to a source of energy.
Unidirectional can be identified by line/load or in/out terminal marking on the device and also on the diagram.
Solution:
The RCBO’s below are bidirectional and switch the neutral conductor. They can fit onto a standard Hager consumer unit busbar taking up either one or two ways.
