## Short circuit rating calculations - 08/06/05 02:06 AM

I've recently run into a situation that I havn't thought about since my days as an apprentice.

I need to calculate the short circuit rating of a couple of machines that are not currantly approved for use in Canada. As part of the certification, they need to be labelled with voltage, FLA, hz, phase etc as well as short circuit ampacity.

These nachines have an electric motor, 120 volts, and some mechanics for a printing shop.

Can anyone tell me if there is a calculation available to complete this job.

Any help would be appreciated.
