This is what Im working on I think you will get the point I am trying to verify
Compressor is rated 7A (Max) running current 3A Fan is rated at 1A. toatal load is 8A but more loke 4A when running
2.5mm cable from DB to Compressor
1.5mm cable from Compressor to Fan
D.B is fitted with a 10A C type breaker.
After doing the V.D calcs the drop is far less then 4%
As you can see I have used a slightly derated cable from Compressor to Fan (I could have used less) so the breaker at the D.B will protect all the cable in the circuit.
Everyone agree? I bet you dont
