Gas removed for New Electric all over flat

[sl1210]

Hi guys,

Could do with some advice on a job I've got on this week.

A lady from holland who has a flat in a block of flats in London has had her gas supply totally removed from her flat, as she is dead against it. Now the problem is she only has a 60a fuse at the rifle board supplying her flat. A guy from EON came today to supposedly upgrade the main fuse to 100a and tails etc. But due to some miscommunication he thought he was only coming to remove the 60a fuse to kill power to the flat. Now when he came he said it wouldn't be easy to upgrade the rifle board fuse, as the service head only had 3x100a. And that to upgrade these would mean cutting off power to the whole block, and upgrading the mains from the road.

This is the new load

1 x 3kw? water heater
2 x 2kw heaters
1 x 1.5kw heater
1 x 1kw heater
1 x 1.9kw steamer
1 x 3.6kw cooker
1 x 3.2kw hob
1 x 2.2kw dishwasher

+ washing machine, dryer, towel rail

Now all this at full load would definitely use over 60a. Anyway the lady was advised by someone to order a wylex fuseboard with an inbuilt Wylex MESB-63NO 63a Contactor. She also had a dutch kitchen fitter bring over all the new items from holland.
I've never fitted one of these contactor's before and was wandering what would be the best way to arrange the circuits and how to wire in this contractor??? And would it be possible without upgrading the main fuse??

Cheers

the only reason I can think you may need a contactor ( not contractor!) would be if you wished to switch all heaters on or off together, from one point, with one switch.

this switch, marked "heating" would engage the contactor that would in turn supply the heaters ( various mcbs and circuits as per Biffs comment).

i'm not re-wiring the place just modifying a few things. its a pain because most of the flat is on 1 ring. i have used one of the existing radiala to feed the 2 plate hob. and run another radial to supply the cooker. i'm going to use the old 6mm cooker circuit to feed the boiler. the rest is pretty much on the ring.

i have a feeling the heaters may be switch on together as she showed me a thermostat and some sort of controller as i was leaving, so more then likely that is what the contactor is for.

turns out the board that was supplied with the contactor and mcb's was solely just for the four heaters so they can all be turned on via a digital programmer and a thermostat so each heater will need a radial run to it via a switch spur from the 16a mcb's at the board.
