We?re doing a conduit bending/3 phase panel lab at trade school. I don?t have a computer program that I can design circuits yet so I did it the old old fashioned way today. It?s not perfectly aligned within itself in the drawing but I should easily be able to tell how everything is to be wired. The lightest blue lines represent white neutrals. I picked the colours based off what was provided in the worksheets. I?m not sure if they match colouring in the US or not? Some from the other group really struggled trying to figure it out as they were going how the circuitry works while several others had everything drawn out beforehand so once they were ready to start pulling wires it was like paint by numbers. Our booths are 4x4x8?.

You are doing very well, should be proud of your work.

Philip d · Nov 30, 2019

Thank you ,it took a few redraws but hopefully this will work well.

Good job and very interesting. I have question about the smoke. In our facility they have to be in a dedicated conduit with a separate power on E-power. From what I am seeing this is a residential set up but am curious if what I described is for commercial and for a dedicated fire panel and the residential is just a circuit to a smoke head. I have not done residential wiring so just asking because it got me wondering.

Thank you,so far we?ve been wiring smokes off of lights

"I have question about the smoke"
I was taught if the smoke ever escapes form any electrical device or wire, the electricity stops.
Contrary to what everyone tells you, current is actually smoke trapped inside the wire. The smoke has to return to power station and then it goes up the power station's chimney.

Forget Ohm's law, Electricity works on the Smoke Theory. Smoke goes in one end of wire and comes out the other end. And I'm not just blowing smoke.

Evening: You been busy, hand drawn on paper is what you will find on the site from the boss.....they don't normally carry computer drawing programs around, the engineers do that stuff...( just a joke guys), the corrections will be hand drawn....
Here locally on the mainland...the ruling is smoke detectors connected to bedroom lights circuits, or light circuits when smokes are used elsewhere in the house. NO outlets or switched power sources, the thinking being that people do not
normally turn off their lights at the panel or can plug in a device that could trip the circuit.
and i do put lights/detectors on the generator panel if there is one, or when one is added'

The newer smokes, at least 12 years ago were in a circuit by itself. A feed to first smoke, then 3 conductor to the next,next,next and so on. Using 14 /3 conductor - white = neutral, black= hot, red was an inter tie so when any one went off the others also sounded. I have been retired almost 13 years and things have changed so much so no warranty. joe ex-sparkey

Thank you Phil! Did you guys get any snow out of this system? Eastern PEI got hit quite a bit harder than here.

Nope, we escaped, but the girl had to walk home in Halifax, buses and cabs and everyone freaked with a dumping of snow..15 or so
massive gridlock resulted.
we got a good rain soaking and wind, so no lobster traps until tomorrow, but the first and only day of haul back was
wed, and good reports for the day so far.
