Reference to:Regs  525  & Appendix 12 Table  12AOSG   7.2.3

 

The maximum allowable volt drop between the origin of a single phase installation and:

1      a lighting point is 3% x 230v = 6.9 volts

2      socket outlets or current using equipment is 5% x 230v = 11.5 volts

Allowances may be made for motor start-up, transients and voltage variations.
