Unbalanced final ring Discussion ThreadUnbalanced final ring Electrical Advice
I have seen a final ring that had the heavy appliances on one leg (L1). Drawing 19.5 amps in total, one leg (L1) was drawing 82% of the 19.5 amps of current. If the ring went up to 32 amps the 2.5mm cable would in theory be just safe enough under the 27 amp maximum.
My question is, if 32 amps worth of appliances were drawing current on L1 would the 82% be reduced as there would be more resistance on L1, so more current would be sent around L2, reducing the 82%?
I have not seen any tests on this. It would be interesting to see some.
