Fitting 240v now.

[waynes world]

Hi all

I have decided while i am it and close to completion on this refit i want to add two 240v sockets on FAFFER.

This is a quick diagram at the minute using an RCD. The usual way is to go with a garage type but i have come by these socket RCD type.

Socket RCD

Anybody had an experience with these socket RCD`s ?


Also thoughts on my wiring please while i am at it


Thanks

Wayne

You'll want RCD protection on all of the circuit incase of anything happening.

That is what i thought the socket RCD would do,much the same as a garage RCD but with sockets.

So only way is with a garage RCD.

 

[matthewriches]

Garage c/u with 1x 40A RCD, 1x 16A mcb for sockets on a radial and 1x whatever appropriate for battery charger feed.

Them sockets are suited to a chicken shed or a garden.

I have this on my shopping list but it is 63amp, i will see if i can find a 40amp then.

There is only one socket in the cabin so no series wiring needed for multiple sockets. Unless i wire the socket and charger in series.

new diagram, any good ?

It doesn't matter that it's 63A, the important thing is that it has a 30mA RCD. You don't necessarily need a socket for the charger, you can hard-wire it in to the consumer unit.

Only the left socket will be used from the mains

Really?? A dual gang socket with a single built in RCD is unlikely to have separate feeds.
Also chaining RCDs (one in the consumer unit and one in the socket) is not normally a good idea (unless they have very different trip currents, which you will not want here)
Best for what you describe is:
Consumer unit as pvb describes: 30mA RCD, capable of handling over 20A. 2 mcb installed one for charger , one for a single socket (the left one)
The right socket, I guess you intend to power some other way (inverter perhaps) It would be bad to have 2 sockets powered by different supplies in the same unit.

I've fitted a combined RCD and 3 sockets, as used on camp sites. Like this:- https://www.ebay.co.uk/itm/Crusader...287601?hash=item1ed72111f1:g:RAUAAOSw~3paT4Q6 Bought new from Aldi/Lidl a couple of years ago. If you get one of these, make sure the sockets are 'sideways' orientated, not vertical as on mine as there is not enough room for the lead from the plug.

That will be perfectly satifactory. The 63 amp figure is the maximum safe current it can carry. It is not the tripping current,

The important tripping currents are 30mA for the RCD, to protect you from electrocution and 6 amp and 16 amp for the two mcbs... which are the currents above which they will trip to provide overcurrent protection , as a fuse would do.

No.

Fit the consumer unit from Ebay. Connect a normal socket to the 16a MCB and the battery charger to the 6a MCB if it's rated high enough, if not get a 10a MCB in its place.

You don't want two RCDs, but you do want MCBs.

Hey Wayne! Nothing to add to the above, just saying hello and happy to see you around again. Any updates on the restoration?

Hi there, hope you had a good xmas and new year, me not to good as i have been ill and just over it now but for the darn cough. So, not got anything done really but for fitting a socket and and a ammeter, that was enough as my head was gone. Will be updating soon


Thanks for all the replies and i will read through them tonight, just one question on one reply.

Why is it bad to have separate sources to a double socket. As in a double socket has mains to one socket and the other socket has power from a inverter? Just like having two separate sockets but these are side by side.


Have a good day all

Perhaps not 100% applicable to your case but with two separate supplies, eg via different fuses, it would possible to isolate one supply , not realising that there was a second supply which is not isolated and creating an unexpected danger if accessing the wiring although the electricians who survive the longest are those who check everything is dead before sticking their fingers into the wiring,

BUT

can you get a double socket in which the two sockets can be separately wired ?

1. Most double sockets are internally connected. You make one connection to the unit and solid busbars connect to the actual outlets so they are not electrically separate.
2. If you are feeding one socket from one source and the other from another source, the sources will not be synchronised in phase. Phase will inevitably be different and will wander. If one socket is at the peak of its voltage (upwards of 320-380volts depending on the source - remember UK is 230vRMS +10% or -6%) and the other is at its minimum of say -320volts then you have around 640volts to near 700 volts difference between the sockets and hence appliances connected to the different sockets. Check you wifes insurance before letting her dry damp hair with a hairdryer in one socket and straighting tongs in the other - as its AC this difference occurs for a fraction of a second every cycle but it would still be damaging.

What inverter do you have ?

 

[waynes world]

This is the double socket i have fitted.

https://www.ebay.co.uk/itm/CBE-CLIN...289105?hash=item4d46156551:g:jqQAAOSwZd1VXwXO

So it is two separate sockets in one housing and not connected.

What inverter do you have ?

We have no invertor yet, may not yet either. Just planning ahead.



New diagram, the using the 16amp for the socket and the 6amp for the charger.

That diagram is correct.

The socket is OK to use split, as you describe.

If you fit an inverter and connect it to the other socket be mindful that it will have bypassed the breaker and RCD, so make sure the inverter has a built in RCD.

Yes, i will worry about the inverter if we get one. There are so may to ok at thats a job in itself.


Thanks for the thumbs up
