Ceramic hob swop -- shunts/jumpers/bridges question

[dga3240]

I am new here, so please excuse what seems to me to be a stupid question! I am replacing a cracked Matsui MCE417C-C 250v 6000W 25a fused ceramic hob with a new Hoover HH64BV H-Hob 500. The Matsui had a multi pin connector by Kado 1/5 and the Hoover a Kado XT with six connectors. Both hobs are dimensionally the same size (so will re-use the hole in the worktop) but the Hoover is 220-240v/380-450v 2N 50/60Hx. I am beginning to wonder if this is indeed a straight swop?

I understand about the legislation and will get someone to sign off on the transfer.

Secondly, the Kado XT seems simple enough to wire up using the original wiring (both hobs are 4 ringed and the Matsui has lasted at least ten years). But inside the new connection box I need to use two jumpers. I tried wiring up the box with the jumpers but the screws simply don't clamp down hard enough to make a firm contact with the jumpers which simply drop out, unless they are doubled up or beside a wire in the same hole. I was so convinced the connector was a Friday night cock up, with stripped threads, that I bought another Koda XT. But it is just the same. Using two jumpers, one on top of the other so they make 'one' thick one, does help but then I am left with too few jumpers!

Can some kind person save my sanity?

I do not know why that should be so, but

can you not just use some washers?

You are doing something wrong.
Post a photo of the connection box and the wiring.

You don't and you won't.

Thanks for the replies. Not a good photo I'm afraid. Wires are not pushed home or clamps tightened down.

I think Scottish law will be a bit different to English law, if past experience is anything to go by.

Not the type I had in mind when I suggested washers.

However, you will see from this video at 0:47, that three bridges are used.

It doesn't really make sense to me.

Yes, I saw that video. also that three bridges were used....but I think I must have read every other reference to those connectors on the internet and no where is that mentioned! Very odd! I think only three bridges were included with the connector I purchased. But as I have an extra connector, I have six bridges of course, not three!

Does the wiring otherwise look correct? I have a man locally who can check for me, but I like to get these things right.

Thanks again for your help.

I can't find any instructions.

I can't find any instructions.

I don't know if this link will work but it is the nearest I could find: https://d15v10x8t3bz3x.cloudfront.net/Libretti/2022/12/16703574/70005172-UM

It matches the instructions.
The screws for the earth connection to the metal panel are missing.

The only other suggestion is to make sure all of the terminals are fully open before inserting any wires and links. That style uses a rising clamp arrangement and it may be possible for the link to go outside of that clamp if it's not fully opened before inserting the link.

I don’t know know what is happening here, but it doesn’t look good to me!

Yes, but I have those so not a problem. I have examined the connector pretty thoroughly using a magnifying glass and I also have the new connector to compare it to. I inserted the wires using long nosed pliars to ensure they are fully inserted. The clamps where the wires are inserted are screwed down solid and they don't move but no matter how tightly I screw down the clamps with just one bridge, I can't get it tight. I can with two bridges. I did raise a question with the seller (twice) but no reply, I have also raised a complaint with Ebay thinking it is just a faulty connector. Then the new one arrived, just the same apparent fault.

That's reassuring. Thank you for that.

I think that is just because it is a bad photo! But I do know the earth wire should have a green sleeve which is missing.

...and the wires should be dressed something like this so that if the cable is pulled out the earth will be the last to be disconnected.
