Metal consumer unit ....your opinion after fitting.

[Rob_the_rich]

I fitted one of SBS Dave's amd3 boxes last week. I only used one of the rectangular knockout at the back for cable entry, and set the box on plastic trunking to bring it forward. I did have a bit of trouble knocking it out, but managed it. The edges weren't sharp, but used grommet strip anyway.

The holes for fixing the CU are upside-down-keyhole-shaped and the slot where the screw head sits is a bit short, so I used washers. I could imagine an upward knock would detach the CU. There was a large round knockout on the side close to the main switch, perfect for those new glands which take all 3 cables. That one knocked out easy.

Overall I was happy with it, and would use one again. Thanks Dave.

No problem with the "FECKIT" (previously known as the "Fookit"):

Ok so drilling a pilot hole is no mean feat, the use of a power tool to tighten the q max is ok then just  searching showed using Allen key to tighten? 

i usually use a hex bit into 3/8 ratchet, much easier than an allen key. you could use impact, but i dont

Hum! Ratchet drive good idea!

I use a ratchet,

You are right about the knockouts, M107 and in fact  I drill out the 4 tabs on the back knockouts, before bashing them out.

Dave I do the same after the first board I used buckled a little when I gave it a good clout to knock out the back KO.

Yes I use washers.

Dave there is nothing wrong with your units...............they comply & fulfill the requirements.......job done.

I am silly aren't I!

The FECKIT in the picture is no good as the 32mm Starrett uses the larger arbor! The Oops is the one.

Or you could buy one of these thrust races and make it even easier:

got them fitted to some, but on others (smaller sizes) they dont work properly and get in the way more than they are useful. they are also cheaper elsewhere if look for a standard thrust bearing with the relevant size hole instead of q-max thrust race

keep them oiled and they work much better
