gauge of enameled copper wire

Tony,

what is the gauge of the copper wire we are using for the coils? I do not have a micrometer to make the measurement myself.

It's 0.18mm dia., a slightly thinner wire would have made coil winding easier but increased resistive losses. It only just fits on the piece formers.

Re: gauge of enameled copper wire

Would 33 AWG be an adequate substitute?

It would work OK on the baseboard coils but might be a bit tight for the piece coils.

Re: gauge of enameled copper wire

If you have a choice go with the 34 dia.
