Gridswitch fuse spur?

[Mike Blair]

alright guys i have to get a 8 way grid switch but i have installed one. currently on a job where the electrician has left and i have taken over his job and has been a utter nightmare... there designer wants to use a 8 way grid switch 20amp double pole but someone was saying the fuses go in the back of the switch?!? never seen this i think hes confused! o_o

You can get fuse modules and/or flex outlet modules depending what exactly is needed. Of course they will take up a module each though in addition to the switch module!

You would have to specify your requirements more clearly.
Generally if you have a 20A DP switch then this is feeding a socket, for which the fuse will be in the plug so a fuse is not required at the switch.
If the 20A DP switch is not feeding a socket then is fusing down required, as the circuit should be protected at origin.
If you are switching four items then you can have both a switch and a fuse in the 8 gang grid.
I certainly would not recommend having fuses behind the switch plate as this is an inaccessible and inobvious nightmare.

could someone show me a grid with fuses and switchs i have never seen one tbh o.o thats why im confused as hell. and no one else on site "designer" etc knows -.-

 

[Mike Blair]

instead of fuse spurs everywhere there using the grid switch so its all in one place

i see so i would probs have to get a 8way wago to split the feed into each fuse o.o haha

 

[telectrix]

no, you loop the feed from 1 module to the next, then the next, etc.

 

[Flanders]

No you feed to your fuse then from your fuse to the switch and then from the switch to the load. so in an 8way grid you could have 4 outgoing loads

 

[Richard Burns]

For an 8 gang switch you could arrange things like this to provide witching and fusing for four items.

and wire like this

Yes I do like these but I don't think they do an 8 way face place that the OP requires

They do a 12 and 18 way though. By the sounds of it more than 8 ways will be needed as the fuses haven't been allowed for.

Personally I would feed the switch modules first and then the fuses. It means you aren't inserting or withdrawing a fuse into an energised carrier then if the switch is open.

...open?
