Do wires expand overtime?

Yeah, if they're normally current carrying

It expands and contracts. So over time the connections can come loose.

^^^^^

Thanks guys. Got it all figured out.

Good to hear

@John O - if you need a good laugh https://youtu.be/-WiN0vf4G9s

He's really crude but funny, "The Builder" on the same album is so funny.

Kek, nice

Yes the by product of electricity is amps, the by product of amps is heat. As a circuit is used it heats up (expansion) and when its not used it contracts. This is also a reason derating factors are used for counduit exposed to the sun

Thus is the main reason copper is used over aluminum these days

Aluminum is trash

All of our services are aluminum. We usually use aluminum for anything over 100A because of cost

Oh my

>quantity

>quality

>choose one

Bruh, I don't run the company

I would say that the majority of electrical fires ive been to has had aluminum wires and zynscos

As long as you use pertrox or something, and torque everything down, it works good. I've been on a lot of huge, high profile commercial installations that use aluminum.

I would definitely advise scheduled harmonic checks. The aluminum conductors have a history of shifting

But i know most other contractors live by the it only has to last one year and my assets are safe rule

You would be amazed how often i find service conductors loose or the dreaded arcing from a loose neutral

My company included

@John O - check this dude

Thought it was an old phone box

1909

That white stuff on the back of the door is asbestos.

@RevStench extremely cool. Is that porcelain?

I would think it is, but I don't know for sure.

That's cool af. What do you think it is? Main service? Those are fuse holders, right? I don't see stuff like that around here. I was born in a house built in 1820, but the town I grew up in, the oldest buildings were from the 50s

I wish I knew for sure, those are fuse holders for sure, it's on the 2nd floor, so I'm not sure if it's the main.

I didn't have a lot of time to look at it, I had to run across town to help a lady out kind of last minute, it's Derby weekend so it's crazy around town right now.

@RevStench lol you always find the craziest stuff

Haha these old homes have really neat stuff in them.

I bet it was a box added for something cool like a shock therapy machine.

Based

Electricity is based

I love it when a plan comes together

@Rogue How's it hanging, bro? Haven't heard from you in a minute
