Icu: Ultimate short-circuit breaking capacity. Ics: service short-circuit breaking capacity. * I test what parameters (voltage vs current) affect the overload protection of a circuit. * I demonstrate the instantaneous breaking / tripping capability of a circuit breaker on an oscilloscope under various loads. * I show circuit beakers that are designed to cater for electric motor start-up inrush current with an adjustable instantaneous trip setting. http://en.wikipedia.org/wiki/Circuit_breaker#Standard_current_ratings Understanding Electric shock / Electrocution: http://en.wikipedia.org/wiki/Electric_shock ------------------------------------------------------------------------------------------------------ My website and forum:- http://www.mjlorton.com Donations and contributions:- http://www.mjlorton.com My techie channel MJLorton - Solar Power and Electronic Measurement Equipment - http://www.youtube.com/MJLorton My Techie Amazon Store: http://astore.amazon.com/m0711-20 My other channel VBlogMag - For almost any topic under the sun! - http://www.youtube.com/VBlogMag My VBlogMag Amazon Store: http://astore.amazon.com/vblogmag-20 ------------------------------------------------------------------------------------------------------ =================================================== Video sponsor, Pass Ltd - their websites: At checkout use the discount / promotion code "mjlorton" for 5% off. http://www.tester.co.uk/?cmid=QmhzQjcxYjVlc1E9&afid=bFcwbzliNzVDc289&ats=K2EyUjZNTDh3UTA9 - Test Equipment and Test-meter suppliers and http://www.calibrate.co.uk/?cmid=QmhzQjcxYjVlc1E9&afid=bFcwbzliNzVDc289&ats=S3Yxd2tOMjVISzA9 - Calibration and service of test equipment =================================================== $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ Bitcoin (BTC) Donations: 1K7PeF55e7ssE7W3WVCoa7c4j2PHzy6ASv $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ ********************************************************************************** Music clip from Youtube Music Library - Phase Three by Huma-Huma **********************************************************************************
