  • Mike I am setting up some new 277v led fixtures in an existing Walmart and the circuit is to b controlled by building management and on a dimmer system it runs through a novar controls system with minio. I am. Infused as to the wiring method lights come with two low voltage for dimming prints call for 277?tolight and then 2, # 14 from novae control. I am assuming that novae system is tied into the panel I am feeding lights with can u give me some input in this type of system

  • Raceway Chart: It shows 400amp protection for 500mcm conductors using 60 degrees. Since @60 deg. 500mcm is rated at 320amps. Wouldn't we use a 350amp breaker as overcurrent protection. I was assuming copper conductors.

      Please check the table again, the "*" only applies to the 40,48, 64, 72 and 80A loads.

  • Hey Mike Great course I got master electrician book package. I watched some videos on u tube also. I was more than pleased with the way your team organized this test prep. I took North Dakota test on Monday and I feel your product was a real asset. So much information. I'm in my 50's and still taking tests, I have to laugh. Can't sit still.

    Thank you To Mike and your team, I feel like a real electrician now that I'm ready to retire! Kevin
