the sub board is for a static caravan fed from a 3 phase board in a garage 137 meters away the cable will be surface 25 mm 2 core swa fe from a B50 ib did the maths and it worked out that iam not within the limits was just looking for advise thanks a lot guys sorry about the way i asked the questionThat completely depends on what volt drop is required for the final circuits from the sub board. The maximum permitted volt drop for a circuit should be from origin to final circuit end. The designed volt drop for the sub main should take this into account.
