Don't let a "dead" box put you in the hospital. In this video, I show you exactly why "pulling the plug" isn't enough to guarantee your safety on an HVAC call. 0:00 The "Shock" - Why you can't trust the plug 0:45 Identifying the "Rigged" Disconnect 1:30 Setting up the Multimeter for Safety 2:15 The 240V Leg-to-Leg Test (The False Positive) 3:00 The 120V Leg-to-Ground Test (The Real Danger) 3:45 Conclusion: Always Test, Never Assume I found a disconnect that was rigged internally, and even with the handle in my hand, the contactor was still LIVE. What I cover in this video: The "Jump" Test: Why I got hit even though the box looked safe.The 3-Point Meter Check: Why you must test Leg-to-Leg (240V) AND each Leg-to-Ground (120V).Rigged Boxes: What to look for inside a disconnect that’s been bypassed by a previous "tech" or homeowner.⚠️ SAFETY WARNING: This video is for educational purposes only. Electrical work is dangerous and can be fatal. Always use a calibrated meter and follow LOTO (Lock Out Tag Out) procedures. If you aren't a trained professional, do not attempt this. Note: Even when the meter showed 0V across the legs, the leg-to-ground test proved there was still lethal voltage present. 🛠️ Tools & Parts used in this video: Fieldpiece HVAC Meter: https://amzn.to/4ujakFD (As an Amazon Associate, I earn from qualifying purchases.
