“I’m working in this newer building. It’s about 4-5 years old 250,000sqft fit up. I noticed all the transformers are hard piped to junction boxes mounted to the side of the transformers. I took a look at one and it seems there are no bonding conductors pulled in the primary or secondary. After a bit of an investigation it seems if the conduit was a metal raceway then there was no bonding conductor being pulled. No bonds pulled to panels, transformers, electrical equipment, Ev chargers and power a”
“So I took on this job to figure out what was wrong with a client mini split system giving E6 code after multiple trials and error changing board switching heads connections etc I came to the realization the wires romex coating has holes in it and as such was causing all the wires to oxidize which is bad for sending signals so ran the wires from the window straight to the condenser and it worked so now the client is asking to run the wires to the unit discreetly which would you ld be easy if whoe”
“Electrical Engineer here that doesn’t know that much about what you guys do on the field so I’m trying to learn. I got a 1000A coming from a bus going into an enclosed circuit breaker then from there to a large chiller for a mall. I’m calling out 3 conduits with 3 #400’s in each going to the breaker. If the breaker only accepts 3 connections (1 for each phase) how do you guys combine 3 large conductors into one? Do you even do that? submitted by /u/famas1631 [link] [comments]”
“Recently did the service for a 20+ apartment complex. Consisted of 3 separate 600 amp services all fed from a common utility transformer. Utility finally came to hook it up, the day before everyone moves in, and it doesn't work. Each of the 3 separate 600 amp breakers are not functioning--2 are passing only 1 of 3 poles through when turned on, and 1 is passing only 2 of 3 poles through when turned on. Meters are not in (except one commerical meter for a house panel that is turned off), so th”
“I know I'm probably going to get teased a bit for this. I've been doing commercial electrical for 5 years, and then some service/residential with another company in the same time. My question is when running conduit through the walls of a shop, do you guys just make the hole large enough for the fitting to pass through, and have the fitting inside the wall? My goal is to have the disconnect flush in between the ribs. Otherwise I know I can put some shallow strut up and make the hole cond”
“Can someone help me? I'm not sure what this yellow wire is and if it's okay that it's exposed like this. Any help would be appreciated. submitted by /u/versus54 [link] [comments]”
“3 days worth of work Figured if you need to find an wire you wouldn’t have to look hard sense its individually tie wrapped. Just need to land main breaker wires submitted by /u/Hungry-Mistake-7615 [link] [comments]”
“Something I enjoy doing, is making these wires look nice, 500kcmil aluminum. But one thing I think is funny, is that in a perfect world, no one will ever see them again. submitted by /u/Such_Peak_1856 [link] [comments]”
“Got this transformer here, looking to see what you more experienced fellows have to say about it. I did an estimate 3 weeks ago on this building for whole building surge protection, walked past this transformer and it sounded pretty good no crazy temp was at 197°, insulation is rated for 220 degree Celsius. Low hum. Fast forward to today, the owner of the building called and said the transfomer sounds louder then usual, I checked it out today, and yes the transfomer was way louder, I'd say a”
