Discuss UK 3 Phase Motor Star/ Delta phase conversion in the Commercial Electrical Advice area at ElectriciansForums.net

I got this all wired in and working thanks to the help from James, absolutely top man.

Do have a small issue with current imbalance atm, L3 (labeled as output W) on the DPS we get is outputting a might higher current than the other two legs (around 50A) this is causing an overheating issue and the motor to shut off after 15 minutes of operation.

Have tried to wire up W to other phases incase irs a motor winding issue but the high current always follows the W output, pointing towards a supply issue with the DPS.

When under load the current does drop to around 45A but this is still over the rated 30A of the motor and thermal shut down occurs.

Got me stumped again does anyone have any suggestions?

Thanks
