  6. image.jpeg I used a 1 module double pole 16amp rcbo which is a combined rcd and mcb in one device. I only have one circuit and everyting plugs in, fridge , battery charger and anything else such as a leccy heater. I got it here:

    I bought a two module unit enclosure seperately on ebay. Its a bit tight wiring wise but it takes up bugger all space. Forgive the tape over the front but iv lost the blank.
    Unit is under bed bolted with some angle to the side bit the bed hinges bolt on to.

    I like this bit...
    "Cable must be protected from vibration and maniacal damage"
    Could you expand on how to protect from maniacs please.

    See @Dicky s post and mix it with this one, add a little home brew and this is what you get:

    Well, the std consumer units usually have a bus bar for + connections, connecting the single pole MCB.s along the bottom of the mcbs, and a separate bar for the neutral connections.

    Double pole MCBs have live in at the top and out at the bottom and neutral in at the top & out at the bottom so you don't need the bus bars.
    The garage unit boxes are compact but the single pole MCBs are narrow so the opening in the front of the box is made for them. Std double pole MCBs are twice the width of a single pole MCB. That's why for 3 double pole mcbs, you need the width of a unit that can house 6 single pole mcbs.

    Unless you use the sexy narrow ones that matty and marc linked to above. They take up the space of a single pole mcb. Clear haha:beer:

    Right. So if I fork out £50 for the 2 circuit one you linked to earlier I won't have to worry about any of that?

    Yeah, but if you put the product name (powerpart deluxe consumer unit) and the product code into your search engine you'll probably be able to get a bit off from other retailers hic
     
  15. My rcbo and enclosure cost me about 17 quid!

    Sorry, your pic wasn't showing when I looked earlier, now it's all clear...
    Ahh, not going mad then!
    Yes that's tiny and I like. 16A would be more than enough.
    Even better! :)

    I've seen it & it's proper compact. Do you run a plug socket ring wired off that for all the appliances?
     
  18. Yes, well a radial but whose counting.

    Was just browsing ebay. Maybe egged the price difference, but it's not a great hike to go up to the 10A and having seen how hot a 5A one gets I think I'd go for that. OK I understand it'll make as much heat but imagine it's built to cope with more so will dissipate it better and therefore run cooler.
