APPROXIMATE DIAMETERS OF ALL SUNDIAL WIRES

PLEASE NOTE THAT THESE DIAMETERS ARE APPROXIMATE AND VARY FROM LOT TO LOT.

If you have small tolerances, PLEASE ORDER A SAMPLE before committing to a larger order. You can order samples here: samples order page.

Please check that the diameter of each wire you order will fit in the aperture for which it is intended.

The measurements in mm are more accurate than the measurements in inches but vary from production lot to production lot. Please order a sample of the currently selling lot if your tolerances are very small.

Also, please do not choose solely based on what fits. Please make sure the gauge you choose is appropriate for the electrical draw of your device or fixture.

Please note that the parallel wire has two dimensions, height and width, since its shape is rectangular rather than round.

Twisted wire is measured at its widest point.

Note the exposed brass connectors for attaching the AC power source to the rear of the motor.

Thanks to Jim Drake (Florida) for the photos.
