Thanks to both of you for the responses. It may be that the contactor has a 208v coil. I will look again for a voltage on the side, but the only number i could find last time I looked was the AB 69A86. This circuit has been operational for quite some time, so odds are that it is in fact a...
Code Requirements for "finger-safe" Conductor Rail
I'm planning to install conductor rails about 7ft above the floor in an astronomical observatory. The rails are IP2 "finger safe" rated. Where should I look to determine if this is sufficient enough for conductor rails which will be within...
Is anyone able to explain why someone wired this motor contactor circuit such that activating the coil is done by connecting the two leads to the following:
contactor: Allen-Bradley 69A86
lead 1: 120V AC
lead 2: 120V AC - Phase Shifted by 120 degrees
So I guess the difference of the...
