I need a little electrical advise
I have six lights and my box and switch are on opposite corners of the building.
Coming from the box with my white and green to the first light, and my black all the way over to the switch. Can I start my black on the last light or do I need to bring it all the way back to the first where the white starts?
Lighting and receptacles can be on the same circuit but I wouldn't recommend it in your case. One thing you for sure don't want to do is have your lights on the load side of your GFCI's. Nuisance tripping.
I see you are running conduit. In that case, conductor colors are as follows. White is always neutral (ground). Green or bare is always the equipment ground. All other colors are hot conductors. You can also use the conduit as your equipment ground. A good rule of thumb for convenience receptacles is 10 receptacles per circuit. For equipment or appliances like a microwave, AC or refrigerator use a 20 amp dedicated circuit.
I currently have two 200 amp services in my house. One for regular power and one for off peak power. Regular power is 13.36 cents per KW and 4.8 cents per KW for off peak. Service ability charge is $42 per month.
I agree. That is why I used the term convenience receptacles. Those are just general receptacles you would use for a table lamp, vacuum, TV, computer, etc. The others I would run 20 amp dedicated circuits like what you are talking about. I would be curious to see what kind of amps he's drawing under full load. In theory his potential is 48 KW. That's enough to power to easily heat a 5000 square foot house.On that thought; being a fabricator by trade; I would not run near that many outlets on a circuit. I work my tools hard and 15 amp is a minimum, IMO. Also I find string all outlets on one wall to one circuit results in annoying trips ( cause you're working where your working). My preference is minimum of a 20 Amp circuit with every other or every third outlet on a circuit. More wire to run, but not near as many trips to the panel when your getting after it and working the tools. My $0.02
I you run more than nine current carrying conductors in the same conduit you have to derate to 70% conductor ampacities.
