AM2S Section A1: Incoming supply to 3 phase db from main switch

Welcome to AM2S: Incoming Supply to 3-Phase Distribution Board from Main Switch. In this video, you'll learn the correct procedure for carrying out safe isolation on the incoming supply to a three-phase distribution board using the main switch. This is a key practical skill required for the AM2S assessment and is essential for working safely on electrical installations. You'll learn: How to identify the correct point of isolation. The correct sequence for safely isolating a three-phase distribution board. How to lock off the main switch and apply the appropriate warning notice. How to prove your voltage indicator before and after testing. The correct 10-point dead testing procedure to confirm the supply has been safely isolated. Following the correct safe isolation procedure is critical for both the AM2S assessment and safe working practices on site. Take your time, follow each step in the correct order, and always verify that the circuit is dead before beginning work. 👍 If you found this video helpful, consider liking, subscribing, and turning on notifications for more AM2S revision and practical training videos. #AM2S #SafeIsolation #ThreePhase #DistributionBoard #ElectricalInstallation #Electrician #ElectricalTraining #Revision #ElectricalSafety
