Dear Jason,
First of all I also would recommend to hire a qualified technician to help
you with your electrical questions. You may also call you power supply
service company and find out which hook up you have (or check your
electricity bill).
From what you mention in your e-mail I also would say you only have 1 phase
supply. In a 3 phase net you 240V between all phases. (L1 - phase 1, L2 -
phase 2, L3 - phase 3). We you measure between L1 - L2, L1 - L3 and L2- L3
you should always get a voltage range of 208 V - 240 V, depending on where
you live. Between any phase and ground you should measure approx. 110 V. If
you measure only 2 V between any of the connections you either are making a
measuring mistake or you are measuring the same phase.

Subject: [felder-woodworking] 3-Phase question...need answer???
Hi group,
Could someone here please tell me what I need to be seeing inside my meter
box? I have 4 wires feeding into my meter box from the pole (3 "hots" and
a
neutral). One "hot" is a blue wire and resides on the right inside the
meter
can...I assume this is the third leg and will refer to it as leg "B".
Each of the 3 legs measure 120 volts AC to neutral.
There is 240V between "A" and "C", and 240V between "A" and "B"(the blue
'3rd' leg).
I only measure 2V between "C" and "B"(the blue "3rd' leg). Is this right?
Perhaps this is Delta connected rather than a Wye connected? I'm not too
knowledgable on 3 phase.
Also, "C" and "B"(the blue '3rd'leg) are the 2 legs pulled right out of my
meter can into the 240V breaker can for my air conditioning unit.
I feel bad filling everyones' mailbox with "non-Felder" related stuff. If
this is a no-no please let me know, no problem here? But for me, this
electrical project is the last hurdle before I "sign on the dotted
line"...for my new KF700pro!!!
Can anyone tell me what I have, and the readings I should be seeing?
thanks, Jason Gant
