First up, Dustin lays down the basics. A disconnect is not just a fancy word for a breaker; it's a separate device used to de-energize equipment when servicing is needed. No more confusion, alright?
In the MATERIALS section, we explore a variety of disconnecting means—main service disconnects, equipment-specific disconnects, and more. Surprisingly, breakers and even regular switches can act as disconnects if they're within sight of the equipment. 🛠️
Big shoutout to Schneider Electric for sponsoring this video and for their innovative VisiPacT Heavy Duty Safety Switches.
The new VisiPacT Heavy Duty Safety Switch:
First introduced in 1907, Square D™ brand safety switches have a long history of leadership in safety and performance. The new VisiPacT heavy-duty safety switch takes all the trusted features such as the switching mechanism and adds new, standard features such as a viewing window, hook stick handle, QR code for quick access to information, touch safe barriers, and more.

Up next is a hands-on DEMONSTRATION, where Dustin installs a VisiPacT Safety Switch. See how the pros do it!
In the DID YOU KNOW section, travel back in time to the era of Fused Panels. Learn why circuit breakers, which came into the picture around the '60s, are a game-changer compared to fuses. ⏳
In the ELECTRICAL THEORY segment, brace yourselves. Here, we talk about what happens when you CAN'T shut the power off—spoiler, it's not pretty. Proper de-energizing mechanisms are not just a luxury; they're a necessity. ⚠️
Finally, we hit the CODE section, diving into NEC's 422.30:
"A means shall be provided to simultaneously disconnect each appliance from all ungrounded conductors in accordance with the following sections of Part III. If an appliance is supplied by more than one branch circuit or feeder, these disconnecting means shall be grouped and identified as being the multiple disconnecting means for the appliance. Each disconnecting means shall simultaneously disconnect all ungrounded conductors that it controls."
Remember, always stay up-to-code and double-check your work.
Whether you're a seasoned electrician or someone keen to learn the ropes, this video's got something for you. Don't miss out! 🎥👷♂️
