Dual Heat Radiator Connection -Earth question!

[Sdfuk]

Hi

a bit long winded to explain but bear with me...

I have a dual heat radiator connected via a fused switched spur. In order to turn the radiator on I had to do so via the spur switch which was awkward and I was always leaving the thing on.

I purchased a thermal control plate for the towel rail element (Tesla TCP100) and connected successfully - all works, easier to access and now has a 2hr function so it turns itself off.

The original wall plate had 6 terminals:
Load L,N & E
Supply L, N & E

so very easy to see where the earths went.

However, the new thermal control plate only has 3 terminals N (both load and supply Neutrals), L (for supply L) and Lt (for load L) - there are no earth terminals / connectors.

How should the earths be connected?

Can the the two earth cables be joined together? The reasoning for this is that ultimately the earth runs back to the fused spur socket? This is what I've done.

The only other way would be to purchase a mounting box with an earth connection and connecting the supply and load earth cables to that.

many thanks for any help.

yes, join them together either by crimping or if you don't have the equipment, use a piece of 15 A connector block

Oh, and if the back box is metal, better to join to them both to the earth terminal in this

Great, thanks for that. Seems like it's ok. Wiil just check the connector that I used.

Cheers
