Hey man super interesting vid. im an apprentice starting in traffic trying to understand wiring cabinets and generally how everything works. what are overlaps exacly? Im assuming theyre for the arrows? but dont you just have to wire for the amber and green but i see that red is also wired into that phase?
Everything metal gets bonded to ground through mechanical connections to grc conduits and ground rods in the controller cabinet and service pedestal. If the conduits used are PVC we pull ground conductors and still bond to ground rods.
Are the physical lights wired together since all of the reds would be illuminated together, or does each individual light have wires homerun to the cabinet? Also, why do they use a separate light for the flashing yellow arrow, and not just flash the yellow arrow that's there already? Seems like a waste.
I love your channel so much thank you for what you do!
this has been an interesting channel to watch :o

How come no grounds with your phases? Aren't these compliant with the NEC? Just asking!

Check out the newest video!
What gage wire do you use for the signals, I am an electrician from NYC
#14 on the conductors going to the LEDs!
Wondering if the old metal signals had ground wires.
How come you crimping the connectors with the wrong part of the crimping tool.
It’s an insulated connector and I use the insulated crimp part of the tool.
@@Trafficlightdoctor You are using the uninsulated part but I see it alot I love Your Show.
@@customsteve i have the same crimps hes using the part for insulated connectors so it doesnt break the insulation on the forks.
