    Acceptable incoming voltage from substation to shop outlet

    Hi, I was wondering if anyone would know what the acceptable minimum and maximum on a single/three phase main incoming voltage should be. From what I have gathered you have a tolerance of +10 230V -6. Could you also quote from where it is mentioned in the wiring regs. Thanks.
