3 Phase for amatures....

[Andy™]

unless its changed in the new AM2, the old AM2 had a neutral for the control gear

the picture of the dol is like the one i had to wire up for the AM2 i ran from the db L1 brown,L2 black ,L3 grey, cpc ,and a neutral to the top of the dol and wired it up i put the neutral in a connector block and left it in the inside of the dol.then i ran from the test box (motor) brown,black,grey,cpc to the bottom of the dol and connected that up there was no neutral at the test box.

i take the neutral i left in the dol was what they failed me for when i tested the motor circuit it was fine.i should of taken the neutral out but forgot when i was running out of time.i had never wired one of these up before and the college never showed us on the 2 day refresher course because they said they did`nt no what was on the AM2 rig,funny that because when i done my test the lectures were never out of there.

could this be why they failed me ?

Searley - is that picture the same as the one in the AM2?

Is that all thats required for the motor circuit aswell as the motor?

Sorry I misread the post. I was going to get all technical about slip ring 3 phase motors then I realised it was amateurs you were talking about not armatures......

No, motors use all three phases for each motor. However a factory floor will have it's lighting split over all three phases (30 lights on red, 30 on blue, 30 on yellow).Each sub-main will have the load on that sub-main balanced out over the three available phases

Red, yellow blue what are these I thought that it was Brown, Black Grey or L1, L2 L3:run

Nah. Quite like me vetting.

Gets more money as a vet as well
