Guys I've done very little commercial or open wall work. My question is I'm wiring a work shop (40 x 40), open beams and purlins. Sould I use BX as my trunk line then enter a junction box then use EMT to drop down to the recepticals and light switches.
Also since I will be useing single stranded wire (black, white, & green) should I run my ground (green) conductor all the way back to the service panel or is it acceptable to bond the ground in the metal boxes useing the EMT as a path for the ground as long as I use a bonding ring that the panel.
