"Bought to replace Proteus consumer unit that went pop. The top of the RCCB has 2 connections, where only the one on the right is maked 'L' (for Live). When facing the RCCB, the one on the top left should be marked 'N' (for Neutral). These 2 connections at the top of the RCCB take the source/load power supply. The instructions are unclear, as I firstly connected the neutral cable to brass neutral bar at the top right, which does not work and it immediately trips under any load!"

Review 2 for Crabtree 2-Way Fully Insulated RCD Board Consumer Unit for Garage
"First impressions were of a well built piece of kit. Solid with no thin plastic bits to break off.
During installation you'll find the instructions are poor so read up from other sources if you're unsure. However, it's all standard if you've put one in before.
The other surprising thing is the lack of cut outs on the side of the case for cables which can't run through the back. Fortunately, in my set up, I was able to get all cables through the back so it wasn't an issue.
Both of these are minor niggles. Bottom line is that it will do the job."
