BS7671:2008, 525.1 'In the absence of any other consideration, under normal service conditions the
14
voltage at the terminals of any fixed current-using equipment shall be greater than the lower limit
15
corresponding to the product standard relevant to the equipment.'
16
BS7671:2008, 525.2 'Where fixed current-using equipment is not the subject of a product standard the
17
voltage at the terminals shall be such as not to impair the safe functioning of that equipment.'
18
BS7671:2008, 525.3 'The above requirements are deemed to be satisfied if the voltage drop between the
19
origin of the installation (usually the supply terminals) and a socket-outlet or the terminals of fixed
20
current-using equipment does not exceed that stated in Appendix 12.'
21
BS7671:2008, 525.4 'A greater voltage drop than stated in Table 12A (Appendix 12) may be accepted for
22
a motor during starting periods and for other equipment with high inrush currents, provided that it is verified
23
that the voltage variations are within the limits specified in the relevant product standard for the equipment
24
or, in the absence of a product standard in accordance with the manufactures recommendations.
25
BS7671:2008 Table 12A (Appendix 12) The voltage drop within each final circuit should not
26
exceed 3% for lighting and 5% for other uses.
