RE: Tubing size

I think you are mixing tube and pipe. Tube is measured by OD, pipe is
ID.

Hi All,
When the copper tubing for a primary is discussed as being either 1/4"
or
3/8", is that the industry-standard tubing size or the actual measured
diameter of the tubing?

The reason I ask is that 1/4" copper tubing measures 3/8" in diameterand

3/8" tubing measures 1/2" in diameter.

My 10" coil is going to be powered by nine (9) 15KV, 30mA transformers
in
parallel (4 KVA). If anyone has comments or suggestions, please let me
know.

Thanks!
Tim Walters
