Replacing a Elec Hob With A Ceramic Hob - wiring conundrum

[spruk35]

Hi, I have bought a ceramic hob to replace a conventional electric hob. There is already a professionally installed fused circuit with a dedicated RCD etc. The problem I have is the ceramic hob has two L terminals that are bridged together and I know I only need one, but the connector is so small I cannot physically get the bundle of live wire into just one of the L terminals and the bridge connector. Is it acceptable to run three of the live copper wires from the bundle into one live terminal and the other three into the adjacent L terminal or does the whole bundle have to be in the same "hole"?

Many thanks for any hints.

What is the cable size?

Spliting the cable termination across the 2 points shouldn't be done.

Would a crimp fit?

Thanks Chri5, I think it is 2.5mm there are seven strands of copper it is quite stiff and difficult to manipulate (previously fed the electric hob). The connector block is a conventional plastic block with a screw in each segment and is too small to fit the supply cable and the bridge piece that connects the L terminals, if I could put the cable in a crimp with a flat end that would probably do it, thanks for the suggestion.

As it is stranded, your cable will be at least 4.0mm² or possibly 6.0mm²

What is the rating of the new hob? (It will be on a plate on the hob, and be a rating in W or kW)

Where does the other end of the cable goto? Is there a plate on the wall which it connects into?

I think it is 6.2KW, the other end of the cable goes into a dedicated sealed box on the wall and the consumer unit has an RCD dedicated to that and the cooker which has a separate switched supply box next to the one for the hob.

I also thought about replacing the connector block on the hob with a larger block (although it seems a bit ridiculous to have to amend the innards of a brand new appliance).

The other alternative is to use narrow diameter cable but I was wary of this in case it would be overloaded.

As you can tell I am no sparky but the ones around here either want around £80 for what I could have done myself in 5 minutes if the connector block was large enough or are not interested because it is too small a job.
