newbie seeking advice

[RF Lighting]

I've just been rewiring a kitchen.

I have installed a 4.0mm² supply to a grid switch above the worktop to supply the washer, dryer and dishwasher, with an engraved socket behind each appliance.

A 2.5mm² supply to a 2 gang grid switch for the oven and extractor hood.

A 2.5mm² supply for a socket for the fridge.

A 6.0mm² supply for the induction hob.

All these circuits are in flush mounted steel conduit to keep them off RCD.

Then there is a general ring supplying 6no. twin sockets at worktop height. This circuit also supplies the living room sockets, and is on RCD.

It's just a normal domestic kitchen.

Why? If the demand is more then sure. The kitchen I'm doing has a washer and a dishwasher. Both appliances power ratings add up to 1650w total. If the demand get's increased in the future then the cable is already there and an mcb can easily be replaced.

any ideas how i can earth the lead water pipe ?

 

[RF Lighting]

Is it lead on both sides of the stop tap, or just on the incommer?

I am starting the first fix on monday for another kitchen.

The guy wants no socket visible on the wall as he is having glass all along the back. So we have agreed that there will be a grid switch in the top of the cupboard where it could not be obstrucuted.

1 x Microwave Oven
1 x Coffe Machine
1 x Warm Drawer
1 x Steam Oven
1 x Dishwasher
1 x Waste Disposal
1 x Oven (3.6kW)

Plus there is an island where the ring main will be, and a hob circuit for a 7.6kW hob.
Is it me or are hobs gettin rediculous


He currently has an mk split load db. The ring will remain on the RCD, and the appliances, hob and cooker circuit will not.

What's a warm drawer?

I'm diggin around, found nothing solid yet.

If the answer to RF's question is both, how far into the house is it lead? Then what happens to it?

You can solder the earth to a lead pipe if you are any good at plumbing

Not 100% sure to be honest. I've got the plans here from the kitchen company and it just gives me the applainces and their ratings. I think it may be something like one of those hostess trolley things that keep the food hot, but fixed in the wall.

 

[andrew32]

the lead comes into house then about 15 inches up a compression fitting with copper pipe joins the stoptap then about 10 inches copper before the next compression joint then its back to lead up the wall to upstairs combi boiler
