adding an extra socket

[psmk2]

My kitchen has 4 double sockets with 2 cables going to each. ..I'm assuming they are in a loop.......i need to add one more double to power a microwave and toaster....is it safe enough to take a spur off one

Unfortunately you can't assume they're on a ring main . You need to be sure before going ahead

Whether they are on a ring final or a radial the answer in this case is "yes".

however if they are on a noncompliant multi-socket spur then the answer is no.

Also you may not add sockets to a circuit which has no RCD protection - something else which needs verifying.

My house has the old ****ty red and black wiring in metal conduits.....however the kitchen has been rewired at some point ...probably when the last kitchen was installed.....it looks well done and wired up to the cu.......its the old style fuse box so no rcd..........the double i want to tap off runs the fridge and the new double will only run a microwave or kettle and occasionally a phone charger.........i need to do wiring now but a new fuse box will be getting installed in a few months

the new double will only run a microwave or kettle and occasionally a phone charger

Only? A typical 800w output microwave consumes 1200w, a kettle typically 2500w. Quite large loads.

The socket in question is behind a fridge and wont be used .....only the spur will be used.......Thought I'd mentioned that in the first post but must have omitted that sentence
