Is anyone else.....

....utterly paranoid over the godawful busbar system on many CU's these days?Fitted a Wylex Am3 board today,it was necessary to fit all the devices first and then slot the poxy busar into all the terminals making sure not to get the tabs in behind the clamp....which unless you are a contortionist you cant flaming well see. Resorted to a small mirror in the end,just as well as sure enough the offset tab for an RCD had gone in behind the clamp. Fire proof? They damn well need to be with that busbar system.
Would have use crabtree if CEF had had one in the configuration I needed.....a million times better than any other CU.
And another thing wylex,why does the poxy main switch slide all over the place untill you connect the tails,at which point it'll refuse to stay in the right position,usually meaning everything is about 5mm out of kilter when you try and fit the cover?Crabtree ones stay put,Wylex,Hager etc take note.

(one each for wylex and hager)

Glad I'm not the only one then!
Wasnt aware of a wylex fixed busbar?? I suppose the advantage of the loose system is it allows on site configuration,I still hate them though.give me a crabtree plug in busbar over one of those all day.

Yep, Wylex come in two busbar versions; 'No miss terminal fixed busbar' & 'flexible' versions. The no miss terminal ones are shown in their catalogue as 'NMISS....'! Its hinged by a plastic mount at one end and can be dropped out of the mcb's etc. Its not like the Crabtree set up, so you can still get the busbar tabs in the wrong place.

What do you mean by get the tabs in the wrong place?

The busbar has a series of prongs (tabs) which fit into each device (mcb/rcd) and are clamped into the bottom terminal of the device. With the cage type terminal on the devices it is very easy for the prong/tab to go behind the cage meaning that the tab will not be clamped.As there is likely to be contact it will still work,until it burns out under load.

Sorry wirpuller my post was in reference to Midwest's post about the Wylex fixed busbar but was being lazy and didn't quote him.
You can't not get a positive engagement on the wylex no-miss hence why I am slightly confused about his post.

Me too, I work on controls mostly, not domestic CU's but I carry a small inspection mirror in my tool case. They should be standard kit for all sparkies although maybe a plastic or insulated version might be better.

A phone with the camera in 'flipped mode' is like a mirror that can take stills and movies.

But why all the faffing about when you can assemble it all out in the open before refitting the assembly back in the enclosure?

Initial Install yes,a tad trickier if a device is being added or replaced in a working CU....

We're still a few generations behind with phones in Africa. I got given a Samsung Galazy thing by my network, I lasted 3 days with it before I went back to my Nokia.

If you drop the busbar down and relocate or add an mcb without incoming terminal properly open, unlikely but still possible.

Agreed, but if you make sure the clamp is fully opened back and hold it there with a screwdriver while easing it down into position you can't really go wrong.
