#1 I have a guy on a job 3phase 240/1v high leg They are burning up 3 phase motors Here are the readings on the incoming lines, before the main These have also been checked with a load (Compressor, no difference) A to ground 122V B to ground 121v C to ground 6v (little low)Http//wwwelectricalindustrynetworkcom In this video I am describing how a 3 phase panel is built and how the bussing works in accordance w/3 phase powerNo It is meant for a 230 V phasetophase supply If the motor is designed to run in star a 380V 3phase power supply, then it cannot be connected in delta on the 'same' supply This is similar to applying 380 volt to 2 v windings so clearly the motor would fail
This weeks project is installing a split system A/C The schematic calls for 30 volts 3 phase wiring Since this home needs so much work I will attempt to do the wiring myself I have done auto rewiring but not home wiring The panel outside has two sets of wires in grey looms with what appears to be #8 AWG The colors are white/black/green Connect the wiring to the outlet prongs and tighten each screw down on its wire to secure it in place Connect the red and black (hot) wires to the two brass screws labeled hot Connect the white (neutral) wire to the silver screw labeled neutral Connect the bare (ground) wire to the green screw labeled groundRecommended dimensions of copper wire and transformers for tree phase 230 & 460V electrical motors All wiring and electrical connections should comply with the National Electrical Code (NEC) and with local codes and practices If undersized wire is used between the motor and the power source, the starting and load carrying cap abilities of the
#3 Note that this wiring is only for places with 230V phasetophase voltage not for the more common 400/230V three phase (which can also confusingly be called 230V since that's the LN voltage) It is reasonably common to find the 4pin red sockets used on 400/230V systems for equipment where neutral isn't required, butMotor Wire Size Calculator The Motor Wire Size Calculator will calculate the proper wire size for a given motor HP and voltage This applies to threephase AC motors This calculator will also give you motor amps and recommended breaker size, starter size, heater size and conduit sizeRight now let me give you a simple overview For threephase, you connect line 1 to line 2 and get 8 volts
