How a webinar works

All EASA private webinars are live events in which the audio and video are streamed to your computer over the Internet. Prior to the program, you will receive a web link to join the meeting. 

The presentation portion of the webinar will last about 45 minutes, followed by about 15 minutes of questions and answers.

Requirements

  • Internet connection
  • Computer with audio input (microphone) and audio output (speakers) appropriate for your size group
  • TV or projector/screen

The Zoom webinar service EASA uses will ask to install a small plugin. Your computer must be configured to allow this in order to have full functionality. Please check with your IT department or company's security policy prior to scheduling a private webinar.

Private Webinars

EASA's private webinars are an inexpensive way to bring an EASA engineer into your service center, place of business or group meeting without incurring travel expenses or lost production time.

Ampacity of lead wire and bus bar: Variables to consider

When repairing motors, we often take the lead wire ampacity charts for granted, without giving much thought to how they were developed. Who .gured out how much current is acceptable for specific lead wire, and why are there different ratings for different types of insulation? 

It might be helpful to consider some of the variables that influence what looks – on the surface at least – like a simple subject. And as we will see shortly, “the surface” is one of the variables to consider. 

Since most electric motors and generators use lead cable rather than bus bar, the occasional motor with bus bar leads to questions about “circular mils per amp” for bus bar. Is the current density of bus bar com­parable to that for lead cable?
