Subject: Insulation on Primary windings

Hi All,

Say, I'm designing a new small coil and am deciding on what type of 
conductor to use for the primary.

I'm building a 3"x12" coil and am looking at a conductor diameter (for 
the primary) of 0.125". I could go for copper pipe, or I was thinking 
standard 30Amp Earth wire (which is about the same diameter).

Refering to my subject line, Insulation on the primary, why is it, that 
for every coil I've seen (from miniature to huge), the primary windings 
*never* have any insulation... why is this so?

Therefore, I was thinking that I might leave the insulation on the 
Earth wire that I'll use on the primary... good idea?

Weird thought I know, rather trivial, but it's something I've not thought 
about before...


Thanks!

Catchya!
