    Customer has a dual stage Dyna-Glo 10kw electric garage heater with peak load of 240v/41.66 amps. The manual calls out a max 50amp breaker. Following NEC rules and considering this a continuous load item it would force me to increase by 125% which is 52.075amps this causes two issues: 1) this...

    Hi Everyone, we are working on a very large exterior lighting conversation at an industrial site. Replacing 400W + 1000W HID fixtures w/ new LEDs. The problem is, the existing 40FT+ poles don't have an existing ground wire. To add a ground to these poles would require a $1M+ infrastructure...

    My question is as the title goes. Can I run 50A stove cables and romex throught the dead space underneath cabinets? I've taken on a side job doing some residential stuff and the property manager wants the stove moved from the wall to the center of the kitchen to a sort of bar set up. I'm not...

    NEC Table 210.24 allows a 15 amp receptacle to be installed on a 20 amp circuit. How is this ok?
  13. NEC Code Forum
    I am currently working through Tom Henry's "Calculations..." book for the 2014 NEC. At least a couple of place it uses a factor of 4.5 va / sq. ft. for lighting and receptacle circuits (non-continuous). I cannot find this in the code. Does anyone know where is this "4.5 va" term is in the NEC...

    Some of you guys really seem to know me, others not. My question is, I'm going to start studying my code book again, but I hate just looking through with no real rhyme or reason, so I was wondering if anyone had any suggestions on what to study up for. I'll take suggestions for one week from...

    1) Is there any coding that would not allow the use of a power strip within an enclosure? 2) Is there any coding that would not allow you to cut the plug off of a power strip and run the cord to a j-box to be hardwired, all within an enclosure? 3) Also, can you use butt connectors, out in the...
