In Fuses and Circuit Breakers: Operation and Coordination , you'll learn ...
- How fuses are made and how they work
- How circuit breakers are made and how they work
- The advantages and disadvantages of fuses and circuit breakers
- The selective coordination of fuses and circuit breakers
There are two basic methods of circuit protection: fuses and circuit breakers. This webinar explains how these methods of circuit protection prevent too much current from flowing through an electrical circuit. Starting with a clear demonstration of the basic theory upon which these devices are designed and helpful definitions of terms commonly applied to them, this webinar shows why these protection devices are so important to engineers who, by the very nature of their work, are exposed to various problems and dangers resulting from the use of electrical energy.
Among other things, we will discuss both fuse ratings and circuit breaker ratings. Fuse ratings include current (which is, after all, what causes fuses to open), voltage, amps interrupting capacity, and other items. Circuit breaker ratings include these same factors, but unlike fuses, they are resettable after a trip incident. Since there are places where either fuse protection or circuit breaker protection will be more appropriate, you will learn the advantages and disadvantages to both methods of circuit protection.
Additionally, we will examine the selective coordination of complex circuits for large buildings or industrial facilities. Selective coordination means that, when (not if) a fault develops, only the part of the circuit involved in the fault should be disconnected. As a result, power will remain available for the rest of the facility. Another way of saying this is: A protection device (fuse or circuit breaker) should only operate if it is directly involved with the fault; upstream devices should be sized so that they do not trip or open when the device directly downstream of them opens.
Learn how to prevent significant damage and serious injury through correct operation and coordination of these safety mechanisms.

A site license makes it easy for a company, an association, or a group of colleagues to access high-quality training at a low cost per person. You are responsible for providing a meeting room, speakerphone and internet connection. A signed attendance sheet is required from each group. More on site licenses...
How Webinars Work
It's easy ... and it doesn't take a computer guru to figure it out. At the time of the webinar, you connect to the internet and call in to a toll-free number. You see the presentation on your computer screen. You hear and talk through the telephone. It's just like being there without all the hassle. There's no travel expense and no wasted time in the car.
To attend this webinar, you'll need a computer with a high-speed internet connection (DSL or cable) and a phone line. For your comfort, it is recommended that you use a speakerphone or headset to connect to the webinar. Our system will support both PC's and Apple computers using Internet Explorer, Firefox, Chrome or Safari browsers. If you select a site license, you must provide projection of the internet onto a viewing screen or have a monitor large enough for the group to see.
Online registration is available until the scheduled start of the webinar (subject to seat availability). However, we suggest that you register early as webinars fill up quickly. For questions, call our Customer Service Team toll-free at 1-877-PDHengineer.
Accessing the Webinar
After purchasing the webinar, a printable Webinar Receipt/Access Information page will appear on your screen. Or you can review and print the page anytime by clicking the My Account tab at the top of any PDHengineer page, then selecting Print Receipts and Access Information for Webinars Purchased.
About 10 minutes before the scheduled starting time, call the toll-free phone number listed in the instructions and enter the access code. Next, go to the website shown in the instructions and enter your name, email and access code.
If you need any help accessing the webinar, call our Customer Service Team at 1-877-PDHengineer.
Printing Your Certificate
After completion of the webinar, return to the PDHengineer.com main website and click the My Account tab in the top right corner of the screen. Select Webinars Attended Pending Survey Completion to take a short three to four question survey. The survey is intended to measure how well the webinar met the stated learning objectives. You will then be able to immediately print your Certificate of Completion. You can always print additional copies of your certificate by selecting My Account and then Webinars Attended.
You may cancel your enrollment in this webinar up to 48 hours prior to the event and receive a full refund less a $10 registration service fee. Cancellations made less than 48 hours prior to the webinar, but at least 4 hours prior to the scheduled starting time will not be refunded, but can be credited to a future webinar. Cancellations made less than 4 hours before the webinar are not refundable.
