Underground electrical help

[Tyler62]

Hey Everyone,

I just got a job in a hydro company and im in the engineering department and im mailnly doing design and drafting work with autocad. The drafting is not a problem but there are a few problems with the designing. Can any help me with a few things? They use colours such as red,white,blue, and black when desinging the single phase power going to lots coming from the underground padmounted transformers. Im not familiar with this colour scheme and would like to know how and why the colours are designated and if it even matters. Also, they designate a colour to the transformers themselves. Why is it they do this? And lastly they use designations like double(colour) and triple(colour). is that just identifying a branch of of that colour?

Thanks alot for anyone who replies

There is no standard that everyone uses that I know of but every company seems to have there own. It is hard because every disciple would like there components to be bold and as you known AutoCad assigning plot lines to colors that governs this.

Some people are part color blind so they use colors they can see on the cad.

Try posting this on the Eng tips forum "Autodesk:AutoCad". It addresses Cad issues like this one.
