I am currently extending the ring main in my kitchen (having already notified LABC of the work) and have a couple of questions if anyone can advise me?
I plan to install a continuous horizontal row of sockets and appliance isolator grid switches above the kitchen worktop. There are no gaps greater than a few millimeters between the 3 double mounting boxes. The ring main both originates and returns at the original socket which is located at one end of the row.
1. Which is best practice wrt to cable routing?
a.) Route the return leg of the ring under the mounting boxes?
b.) Route the return leg of the ring through the mounting boxes?
c.) Route the return leg of the ring in a horizontal channel cut immediately below the row of sockets. I realise this solution is unusual, though since the row of socket is continuous, surely anywhere directly above or below
the row is still in a safe zone.
d.) Route cable all the way down to the floor and back up again.
My concerns are:
a.) Damaging cable routed through a crowded mounting box
b.) Hiding cable below a socket box - the next chap along may accidentally screw through this cable when working on the mounting box.
c.) As far as I know, this is not standard practise so potentially suprising/dangerous.
d.) Creating unecessary plastering work for myself
2. Can anyone also advise if its ok to group the following sets of cable in each of their own plaster channel.
Channel 1.
6mm Cooker radial (10.2Kw) PLUS 2.5mm Cooker Hood ( 150Watts)
grouped in plaster for about 1.5 metres
Channel 2.
32Amp 2.5mm Ring cables (x2) PLUS 2.5mm Spur off ring to 13Amp Tumble Dryer socket. Grouped in plaster for about 1.5 Metres.
Channel 3.
32Amp 2.5mm Ring cable (x1) PLUS 2.5mm Spur off ring to 13Amp Washing Machine socket PLUS 2.5mm Spur off ring to 13Amp Dishwasher socket. Grouped in plaster for about 1.5 Metres.
Channel 4.
Central Heating Control cable and supply cables ( x 5 cables ) using 1.5mm T&E
(this was an existing circuit and protected by 3Amp FCU). Grouped in plaster for about 2 Metres.
Any thoughts much appreciated - thanks.
