I didn’t take a before photo

Street light crew is where it’s at

Yep. 1200A 120/208 Cummins standby generator for a single family home. 1200A transfer switch included.

Yes this house costs more than most neighborhoods.

Figured this one out today, just a simple square D lighting contactor but this is my first one. Essentially we have a photo-eye outside, that receives 120V straight off a breaker from the panel. The neutral for this photo-eye goes straight to the neutral bus in the panel. The L2 on the photo-eye comes and hits the coil. The neutral for the coil jumps from neutral bar in the panel. We run a constant hot to the top contact, straight off the breaker. On the bottom contact would be your common 120V with all your lights in the circuit. The 120V feeding your photo-eye stays, it switches L2 hot when the sun goes does, L2 hits your coil, coil pulls in, contact closes, and now your common 120V to all your lights gets 120V from the constant on the top side of the contact. This is a good simple way to learn contactors. I made a little jigged drawing to explain it a little better

My partner is an electrician and I sell his overstock items. There was a Servo motor in a pallet lot at a recent industrial auction that he wanted. He takes the motor and picks through any other items from the three pallets that he wants.

I'm going through the remains of the pallets to decide what to sell, scrap, or part out. Come across four of these and couldn't figure out WTF they were....one reverse image search later...

Who here is somehow using Tonsil Snares as some sort of electrical tool?!? Because of you there are images of them in use that are now forever in my memory hole.

Of note, these are the only medical type of devices on these pallets. Sometimes in these auctions you come across the random items that clue you in on the type of business these were pulled from. The rest of the pallets are all general purpose relays, pilot lights, pushbutton switches, and heavy duty circuit breakers.

I don't design/engineer the panels i build myself so i can't take any credit for that. Sometimes i also go into the field to install everything. I was also wondering who else works mainly with SAIA PLC hardware and hates wiring the PCD3 like me? I prefer the PCD2 set up more!

Our panels are built for emergency back-up diesel generators for critical installations or generators that run on gas for clients that need some extra power. We also recuperate the generated heat and use it for heating the building.

My company is based in europe so we don't follow american standards.

Got a new Klein long cabinet flathead during a remodel this year. My apprentice got his first hammer that’s not also pliers on the same job in the ceiling too!

Check out the neutral

Was an old gas station, converted to a daycare, now renovating into a coffee shop.
Guess the fire marshal never looked behind the drawings the kids made hung up over this mess.
The more you look the worse it was, gutted it today.

Found a nice Klein stubby, installing some 2x4 Panels.

Ive just worked on installing new heat trace circuits on a pipe in our facility. The full run has 4 primary and 4 secondary circuits run along its length. Where they end and the new begin I keep a healthy distance to avoid possible crossings. What does everyone else do for different circuit spacing on their runs? The gap in the picture is about a foot and it is inside a climate controlled building and will have insulation.

First panel I’ve done myself. Been an apprentice about 8 months, any feedback is appreciated.
