Excellent, thats what I have. Any advice on rcd rating for the second unit? Chris

the connection to the original cu can be installed onto the the existing RCD protected section (its already there for the original buildings that I removed for the new outbuilding) - my main concern is making sure I get the mcb and rcd ratings correct

I'm going to be using the outbuilding as an office for one - so typically a couple of desktops, screens and a laptop on most of the time, maybe an oil heater in the winter or a portable aircon unit in the summer. I already know that my usage is well below 32amps as everything is on an...

so here's the daft question.... If I connect the swa into the existing cu with the rcd at the new cu what rating should the mcb in the existing unit be and what rating should the rcd be in the new cu. SWA is 10mm betwwen buildings chris

main cu is an mk split load 17way with 5 spare 2 of which are rcd protected. the new cu is a wylex 5 way with optional rcd protection

I have plenty of spare capacity in my existing CU on both the switched and RCD protected circuits but was unsure as to whether these could be used as the highest capacity mcb I can get is 40A which I didn't think was big enough given that the new CU will be running a 32A ring, 6A lighting...

Sure - I was just curious

I have an existing consumer unit connected as normal to the meter and need to connect a second unit located in another building at the end of my garden. I understand that the meter tails need to be split to feed the second unit and have an electrician coming in to sort this out but have a...

thanks - I was beginning to think the house was trying to tell me something!!! Cris

About 3-4 inches which is currently a slabbed patio area which I was going to remove and replace with decking.

its 8 inches deep

I was digging the trench today for the SWA cable and found an 8inch slab of concrete that extends the full width of my house and garden and extends at least 2 metres from the back of the house into the garden which is preventing me from laying the cable the requried 600mm. Any ideas on what I...

Wow! This information is extremely useful although to clarify my usage requirements - I'll be running no more than 3 1u rack mount servers at any one time (these are the only commercial grade pieces equipment that I have but even so they are no more than a fairly standard computer in a small...

I am installing LSF crush resistant conduit to in the trench to carry CAT6 network cables and telephone lines but I thought that using SWA meant that I didn't need to put it in ducting? Installing the double earth is not a problem so I'll make sure thats done but I'm intrigued about the high...

Thanks, I'll increase the cable to 10mm in that case. chris
