Hi Ed,

Rea Wire:
http://www.reawire-dot-com/prod_mwire.asp

The "H" is Heavy,
The "NS" is Nysol,
The "R" I believe is Round.
Since there is no "A" for Aluminum, then it must be copper.

The website states:

"Rea Nysol is a dual film solderable insulation composed of modified 
polyurethane resins with a polyimide (nylon) overcoat. The nylon overcoat 
provides a significant reduction in the wire's coefficient of friction 
aiding both windability and the production of compact coils. Nysol has a 
continuous operating temperature of 155°C and is formulated for 
applications where a solderable insulation is desired."

The nominal bare is 0.0253" (same as most charts).
The nominal overall diameter is 0.0276" (their max is 0.0281, so your on 
the higher end). This is their heavy build.

Their nominal overall diameter for single build is 0.02655".
Now, (.02655 - .0253)*.5 = 0.000625" between the bare copper surface and 
the outer surface of the coating, which is thin.

The heavy build, (.0276"-.0253")*.5 = 0.00115" which is actually closer to 
a typical "single build" value for 22 awg insulation (.0013").

Take care,
Bart
