Cpc connection wylex

[Nigel sparks]

Hello can anyone advise what they would do in this situation please. I have a wylex 100amp switch fuse that has an incoming and out going cpc connection which takes up to a 16 mm cpc. I have 16mm incoming and outgoing cpc, however how do I then earth the enclosure and the banjo as the cpc connection has no connection with the enclosure

If it takes10.0 then put a 10.0 into it along with the banjo cpc.

No it take a 16mm only and my cpc is 16mm

This is totally confusing I assume from what you say the separate terminal does not take 16.0?

The main earth terminal which is part of the main switch takes a 16mm cpc max, there is a small earth block which will take a 6mm max hope that explains

You will have to calculate as to whether fitting a 6.0 to it will satisfy.

That’s a good option it’s a shame I have fifteen to do of these

Could it be fixed physically with one of the box fixing screws, then a 6mm jumper to the box's terminals? Or maybe better just a 10mm jumper to lug on piranha / Earthing nut as quicker than banjo, etc?

I will get over with unnecessary work as the switch fuse by wylex is very poorly designed

i still think there are a lot of these installed where the installer thinks the cpc connection is common to the enclosure

It really is a terrible design putting in such a small separate terminal however Wylex may have calculated the worst scenario for fault protection and that a 6.0 would satisfy. I would email them.

They are rubbish considering the price of them, as usual the designer has never had to fit one or they would have noticed the massive cock up with the earth terminal!
The last one of those I fitted I ran the SWA cpc to the earth banjo bolt and lugged the 16mm outgoing on that as well. As stated above an earth nut would probably be quicker!

Yes but if it’s 100amp supply and both 16mm earth connections are used there is no where to get another earth bond from

Yes I agree that’s what I will do thank you

Put a separate 6.0 in. I would personally email them they have taken a real step backward from the previous design.

Yes I will and I I get a reply I will let you know

I’ve fitted loads of these switch fuses. In fact I will be fitting one on Friday coming.

I ignore the earth terminals with Allen heads. I just use the terminal for on the back of the enclosure which you think only takes 6mm2. Unless they have changed the design in the past couple of months (very much doubt) then this earth bar has space for 3x 16mm2 cables. It may look as though it doesn’t but I’ve done it many times. One incoming earth, one outgoing earth and one to banjo.

I asked in #13 If a 16.0 would fit.
