    Hi Guys,

    Looking at Ev Charging and the earth rod scenario on a PME System.
    Looking at A722.3 on page 282 in the BYB but the equation doesn't make much sense to me in all honesty.

    i can see Raev has to be less than or equal to but is 70 Uo 70 x 230 or 70+230 over Iinst( 230-70)

    Having a bit of a mind blank as i dont have a great interest in it but just somewthing ive been asked to look at at work.
