Re: Belling DB900e Mains Block
They are fairly generic, as long as it can take the total load of the appliance and as long as it fits safely, with no chance of coming away and has the correct number of terminals on the rear, it should be fine.
As it’s a full electric range, the max load will be quite high.
Any equivalent GDHA (Belling/Stoves) terminal block will suffice.
If you can post a pic of the rear, I’ll have a look at some of my stock as I have lots of spare ones.
