I did go down this route first then read 7.2.3 in the on site guide lighting circuit a maximum volt drop of 3% of the 230v nominal supply voltage has been allowed the circuit is assumed to have a load equal to the rated current (In) of the circuit protective device, evenly...

Yes but don't you add the distribution Vd to the light circuit Vd to give a total Vd from source to end of circui. Only really need to know if using a 2a mcb is ok for lighting circuit (do florescent lights have much start up current as the three together only add to 0.75 A

Yes after small DB would like to put new supply cable in but after digging up a 10m stretch of tarmac I then would have to go around the out side of house this would too toss and as it's there and it's insulation resistance in over limit and good r1 and r2 seams a shame to not use it.

The VD for supply is 6.08v. If I used a 6A mcb and calculated VD for the whole 6 amps it takes the total over the 3% drop and as there are only 3 florescent lights a 2a mcb keeps the drop just under 3%. Thanks in advance

Hi I'm in the process of installing a small bd in a out house it has a exsiting 2.5 3 core swa supply of a 16A mcb which I would like to utilise I have calculated the Vd for the swa and it's 6.08v I want to run 2 sockets and 3 florescent lights by using a small DB with a 16A mcb for sockets...
