Wiring a Garage consumer unit.

Feb 11, 2014 60 Replies

Problem is (and what's thrown me), is the spare pin in the bus-bar.

What makes you think the bus-bar can't be removed and hacksawed on a bench.

That way your conductive swarf could be kept away from the box.

It is also possible to file off sharp corners.

Your tinsnips are better than mine!

What makes you think I think it can't be?

how do you know this?

An easy solution would be to buy an extra cu fuse an use the spare bus bar terminal.

Dear Markg123, I had exactly the same issue as you post. Why there are no instructions ! ? Is just stupid. It is I fear, just a cost cutting issue? The responses are basically from people trying to sound smug and superior. A day's work fitting this would be an electrician's dream. No doubt they would want to be called for re-wiring plugs and fitting cartridge fuses too?

Excessive costs are a major safety issue, as several High Court Judges have pointed out in gas safety cases.

I didn't cut the surplus prong but just taped it over safely.

It's completely unnecessary to do either (there's enough bare live metal in that region despite the efforts of the busbar shield), but the tape will do no harm.

Cutting the prong is more annoying when you come along and try to add a new breaker to the CU.

This is marked out above the centre aperture with 5 breaker width size segments, 2 for the width of the main switch and 3 for circuit breakers. However the opening centes for just two breakers apart from the mains swich with breakout plastic pieces about 9mm wide on each side that can be removed to allow a third breaker to be inserted. Then all the length of the bar would be needed. I guess the manufacturers thought it was simple and intuitive. Not!

The technical term for it is discrimination.

What's the technical term for replying to a 2 and a half year old thread?

What photo, where? This is a text only newsgroup.

No. There should be 2 neutrals to match the 2 circuits; and 2 CPCs too.

The problem here is you posted through a web portal that does not pass on the pictures to the outside world You really need to post a dropbox link to any pictures etc for those viewing on Us3enet to be able to know what you refer to. Brian

The fact that you've not given any of the relevant information suggests that you don't yet have the skill to do so. Why don't you show us a pic of what you have there already.
