If you go ahead with it I'll post a few more tips than
the wiki article about real life CU swaps.

I'd be interested in that anyway if you have the time?
Would it be worth adding to the article?


John or NT usually add anything worthwhile I post to the
wiki.

So here are a couple of tips that would apply if I had more
than 2 hours to swap a CU!

OK I have woven some extra stuff into the existing article
based on these comments.



Anyone one else (including yourself) got any other tips?

I generally get a couple of hours to swap a CU (plus time to
test). It usually takes me 90 minutes to prep it up and mount
the board with the cables where I want them. The last 30
minutes is fitting the live, neutrals and MCBs or RCBOs.

Wylex RCBOs don't like to grip 2x 2.5mm cables unless they're
twisted together. That can catch people out.




A lot of RCBO do the same.

Add to the list Do a tug test.

Adam (and everybody else) - thanks for the very helpful comments and
suggestions which I will take on board. Good to have some affermitve
feedback rather than a list of reasons why this job can't be DIY.

You will usually find in this group, that the general assumption is
pretty much any job can be DIYed with the right mindset, research, and
practice.

(perhaps with a little caution introduced if it sounds like the poster
is about to qualify for a Darwin award!)

Although I have one more tip

It's probably worth having a practice run of removing the main fuse
before you start. I have very occasionally found that they will not
move. Not very likely to happen in the OP's case as it is a newish house
but still worth checking.

The Main Switch of the CU must be in the OFF position when fitting and
removing the main fuse.
