sparky help needed again.
So a few weeks I asked about how to power up a static caravan that my parents use in the back garden.
Its going to be connected and tested properly however the cable run and entry into the house will ne done by me.
The house end is below.
I believe there is an issue here as their is only a 20Amp slot spare.
The caravan end is below
it has a 32amp and 2 6 amp
so what sort of feed needs to go to house?
30 Amp or bigger?
Do i need a new consumer board?
will the van need earth or will it come from house?
What core size will i need for awc cable?
please help

1. Generally your feed in the board should be larger than the largest switch in the caravan.
2.32amp or above,problem being if what your feeding from is smaller,then that will trip first,so any faults in the van will show up in the house first,inconvenience more than anything.
3.Not really,if it works and is safe that's fine,certainly legal.
4.The van won't necessarily need additional earthing but it won't harm to do,your earth should come via the armoured or you can buy three core,use one of the spare cores as an earth and connect that up to the earthing block,personally I'd put an earthing rod outside the van and use that.
5.I'd go for 6mm myself,better safe than sorry.price wise there's not much in it really,use tlc for your bits,get their really good on price and their gland kits are superb,come with all the bits you need!!!

ah not sure what regs are over there but 4mm sq swa should be plenty with shield an earth connacted to earthing rod outside. dont know why your internal sockets have 32 amp breaker should be only 20 other than cooker and have a main fused breaker and an rcd breaker for sockets only not lights

From what i can see it looks like the best way to do it is, come out of the DB in the house into a adaptable with some 6mm T+E then from the adaptable box in some 6mmSWA go straight into the DB in the caravan it looks like there is already an RCD in the caravan, then find out what kind of current your going to be using and find a breaker to suit for the DB in the house

The yellow colour code on the consumer board, i take it that it is implicitally for a 20amp mcb?
your above info seems very straight forward. I take it as you mention twin and earth i would use the house earth?

sound advice above.if for some reason you do get niusance triping, a main cause could be that you are using an rcd to run another rcd.it can cause noise on the line with both rcds talking to each other

Use the house earth.
And use a Steel (galv) box at each end to terminate the SWA in, it's the easiest way;

Hi, what you need to do to comply with section 7 of the 17 th edition regs is fit a 32amp breaker in place of that spare 20amp one in the house, run a length of 6mm twin and earth to an adaptable box and convert to steel wire armoured cable to run to the caravan. The swa cable need only be 2 core 6mm as you need to segregate the earth at the caravan end and fit an earth rod and connect that to the caravan disboard with some 10mm green and yellow 6491x cable, then test your earth loop impedance and make sure it's under 200 ohms.
Also make sure you connect the steel armour to the house earth only
Cheers Jason

As the size of fuse / mcb increases the slots in the holder and blades on the fuse carrier / mcb get bigger.
That means you can't fit a 32amp fuse / mcb in a 6 amp holder.

As said mate yes thats just colour identification just find yourself another 32A breaker and holder ( i might actually have one if your struggling ) and use the houses earth
