suggestion : do a gallery of Industrial Work

[mdshunk]

this maybe a bumb question but, is the red blue and white taped cables american 3 phase???

They are not really code required to be any particular colors, but here's the "standard" most guys use:

120/208Y - Black, Red, Blue, white neutral
277/480Y - Brown, Orange, Yellow, grey neutral
120/240delta - Black, Orange, Blue, white neutral

How to confuse people by using different colours for phases and neutral depnding up on voltage

thats a whole lotta pipe work, i take it you don't use a lot of trunking, tray or ladder racking, very neat though

Not really. It's permitted, but just not used that much. The only time an electrician here would use cable tray or ladder racks would be in factory work, where the factory will be re-tooled and rearranged on a regular basis. For something like a school or hospital, where things will remain pretty much original for the life of the building, it's all piped. Matter of fact, that second picture above is the headwall (head of the patient bed) rough-in wiring for a hospital surgical recovery room. That's why you see some copper pipes going to what look like electrical boxes. Some of them are oxygen lines, some are ordinary air, and some are suction lines. I'm not sure which is which. I just mess with the wires.

That's a fact. Homes are still just done with cable (with the noted exception of New York City and Chicago, where pipe is the rule), but commercial and industrial work is largely all conduit work. Armored cable is making inroads in commercial work in a big way here lately. Armored cable is permitted to be used in most places where conduit would normally otherwise get used; it just looks uglier.

i agree but a damn site cheaper and quicker to throw in...you can see why

Any of you chaps used the old fashioned timber block for bending tube ?. As an apprentice I had to make one. We had vices too.

 

[montybaber]

I used a block at college and im only 28, just wonder if its still taught?

 

[mdshunk]

I've used the crotch of a tree before to bend conduit, but I'm not especially proud of it. Under the truck tire too.

Never heard of it........and I am 35 !


Our old boss used to make us streighten steel tube out so we could use it again............but this is in Yorkshire!

nice pictures sooo much tube

it seems so very strange to me that you dont seem to combine it with trunking

also a good job with armoured can look very good and neat if done properly

long live the block ..and i knew trees could have nuts but a crotch?
