Sorry Lads and Lasses,

Hi Wams,

after safe isolation, link L1 and CPC of motor circuit at DB, measure between L1 and CPC at 3 phase socket outlet connected to load end of DOL starter, push in contactor of the DOL with insulated screwdriver to make the contact within the starter.

Repeat this using L2 and CPC and L3 and CPC, the highest reading becomes R1+R2 for the circuit, HTH (MEERKAT)

Meerkat,

I presume this test will also include the isolator within the circuit.
