Grid switch fuse wiring help

[drives]

Hi all,

I have some grid switches ready to install for some kitchen appliances, specifically a fridge and a freezer. This includes the 13A fuse within the grid switch.

I was however expecting to see Live in, and then load on the fuse so my supply cable live would connect to L in, and then I'd wire up the load coming out of the fuse, to the live supply connection on my actual appliance switch.

Is L2 the equivalent of the load terminal in this situation?

It doesn't matter which you use or which way round you insert the fuse.

It doesn't matter at all - but I think most would have L1 of the fuse as IN, and L2 of the fuse as OUT.

Thanks both. I was pretty sure it didn’t matter as the terminals are obviously just either end of the fuse but just wanted to check- and that is how I’ve wired it with L1 in and L2 out.

I think your confusion, is caused by the double pole switch, and the fuse, being two separate modules....

Take you like in to 'L SUPPLY', then link 'L LOAD' to 'L1', with a short bit of wire. Connect your L load to 'L2'.

Ah ok. I have actually done it the other way around. I have the live wire from my flex outlet in the wall going into L1 (fuse), then I have linked this to L supply on my switch with a short wire.

As in the supply live connection goes to the fuse first rather than the switch as shown above. Does this matter? I can rewire it no bother (not turned anything on yet) albeit I can now see why people don't like grid switches! Very fiddly to wire up.

Load is definitely the appliance side isn't it?!

It will work, but it obviously leaves the fuse live - if it blows and you need to change it, it will remain live, unless you isolate the entire circuit.

Thanks. Might swap it around then

Is the above switch and the fuse for the same appliance, as too me the above seems like its for two appliances fridge And freezer as mentioned in your first post.
Maybe im reading it wrong but (live from flex outlet into L1 fuse linked to L supply switch ) ?
Wired as you say above a single loads either going through the switch OR the fuse NOT both

I suspect a slight misunderstanding. this is what I'd do: supply to a switch and looped to the second etc

 

[ETAF]

are you then hardwiring the appliances into a connector , cutting off the PLUG - OR will they be plugged In toi a socket attached to each grid switch ?

Yes it is for 2 appliances- intergrated fridge, and separate integrated freezer. I have a fuse and switch for each. I just took a photo of 1 of each.

I have cut off the plugs, and used wago connectors in a wagobox underneath the units to connect each appliance cable to 2.5mm T+E (as in each appliance has separate cable). I then have this running up a void at the side of the cabinets and up to where I have these grid switches.

@SUNRAY I did wonder about doing that but didn't want to overload a single supply cable which I had run from the flex outlet in 2.5mm T+E as well.

You have it fused down to <13amps, so 1.5mm would have been adequate.
