Hi to all,
I went round to carry out a visual ispection before doing above and have a couple of questions if ok
Its a TN-S system Domestic 100amp main fuse , has a MEMERA 2000 ccu with only 1 side RCD protected by a 30mA 100amp RCD
there is a type 1 and b mixed breakers 40amp type b bsen60898 for shower, 32amp type 1 bs2871 for ring circuit but also discovered two radials for in 2.5mm for 1 socket in kitchen and another radial for a single supplying fridge and then onto double in front room for TV,VCR, DIGI BOX AND DVD, 16amp for a fused spur for heating controls only, on RCD protected side and 1 spare way which i am thinking of using for Oven circuit
Then on unprotected side of CCU there is a mem type 1 32amp with a radial in 2.5mm supplying double for socket in attached outbuilding for a freezer in a brick shed
then there is a 6 amp type 1 supplying whole house for the lighting in 1.0mm and also a 1.0mm supplying a bulk head light in alley way and onto another in the shed all udercover from the elements
The main earthing conductor is in 6mm it looks and is connected to a old style MET with BOLTS not very well as some of strands hanging out how do i work out by calculation if this is satisfactory do iI divide 230v by Ze to get the fault current and then do adibiatic equation ????
and will i need to upgrade it to 16mm if i install new circuit for oven
there is NO water bond that i can see but not deffo LOOKS as if there is a 6mm going to bathroom need to check
GAS bond also in 6mm
most of sockets to kitchen are spurred of ring I think
IT looks like i will be better doing a periodic first as there may be other things
and a quick press of theBS4293 100a 30ma RCD and you guessed nothing so looks knacked and will need replacement any ideas if possible to get one
also open grommets on top of ccu
is it possible to get replacement cbs for MEM2000 ccu is it eaton who supply replacements any advice with any of above would be very helpful cheers sorry its a long post chaps
questions will i have to correct all the incorrect items i have listed if i wire new circuit for oven such as
1. installing 10mm for gas and water
2. installing 16mm for earthing conductor
3 removing 32A cb for a 20AMP RCBO for outbuilding and 6amp RCBO for the lights
4. replacing RCD as its faulty is it possible to get 100amp 30mA replacement for MEM 2000 CCU or will a or 80Amp 30mA rcd suffice
5. remove the two radials for sockets that have 2.5mm current carrying capacity exceeded and connect into own 20AMP CBs or RCBO if not on protected side
6. fit closed grommets to Horizontal top surface or enclose wires in conduit CABLES clipped DIRECT to wood then into CCU
any advice greatly appreciated cheers
