Wiring sockets to Sargent EC155

[jfly57]

Hi,
I'm in the process of wiring a Sargent EC155 psu in my conversion at the moment and I have a couple of questions I need answered please.
(a) The installation manual says the white mains cable is for 230V sockets. I have 3 sockets installed. Do I wire them in a ring circuit? it's the only way I can think of that reduces the amount of cabling or do I have to wire each socket separately back to a shared junction with the white Sargent cable?
(b) My fridge is a compressor type so I wire it directly to the leisure battery. I take it I do not use a relay to link the fridge to the battery - is it a direct connection, with in-line fuse, between the two?
Thanks in advance for advice offered.
Joe.

they are uaually wired as radials ie one wire to each socket

The 'ring' description is often misunderstood. Technically, a ring is where all the sockets are wired into a single cable, one after another, and then - the important bit - the wire continues until it comes back to the supply, in a big loop or ring. A ring has a double connection at the breaker supply point.

If you mean wiring each socket into a wire, one after the other, with the final bit not returning to the supply, then it's called a 'radial'.

A motorhome is usually wired as a radial. If you're using 1.5mm2 wire, and the breaker is 16A or less, then you can wire any number of sockets into a single wire. I try to locate sockets for convenience and to minimise trailing wires.

Yes, correct. The reason for a relay for a 3-way fridge is to ensure it only works on 12V when the engine is running. That doesn't apply for a compressor fridge which works on 12V all the time.

Thanks autorouter for both replies. Both your explanations clarifies my queries perfectly.
