Domestic Vs Industrial

[Ryan_Moore]

Hi Sparks!
I am hoping to become an apprentice very soon and I have a question for you all,
What is the difference between the 230v single phase used in domestic buildings and the 415v used in commercial/industrial buildings. Also why is it necessary for there to be a difference, what are the pros and cons of each.


Also I have heard rumours of all new builds now having electric heating, does this mean less work for plumbers and gas fitters and more work for us....or you I should say at the moment, give me a few years

Can I not be your apprentice Topquark I will bring your company to liverpool, it will be a blast!

If there was oodles of work around I wouldn't be on here so much. I'd love to be in a position to take on an apprentice, but no chance of that for the foreseable future

Every spark that walks into the shop says the same thing, especially the ones that stay all day for the free cups of tea! Tough times

Ryan,
To be a top class spark you will have to be able to drink every other trade under the table and be last to bed, then first up in the morning saying what a lovely day it is.

Sounds like what you need to be a top class fella, not just a spark!

Read up on 3 phase induction motors!
These machines are the workhorses of industry, brilliant invention.
Briefly...a 3 phase supply generates a rotating magnetic field in the stator windings which induces an opposing field in the (essentially) solid rotor, producing torque.

Here's a nice little animation showing the generation:
