@mad_electrician_official: Here’s a good one for you. Yikes ⚡️😳 Additional context: Normal circuit was completely off (locked out and tagged out at the breaker). The whip shown in the video had already been disconnected from the normal J-box and was connected to the light. To prevent shutting off all of the lights in nearby occupied hospital corridors, I had planned to de-term normal power first and then disconnect the life safety power. Yes, this takes a little more time but it’s much less impactful for the hospital. After recording this video and completely demoing out the light, I confirmed that whoever made up the light had accidentally crossed the neutrals in the light. This essentially caused life safety to go in through the life safety hot and out through the normal neutral and (vice versa). I misspoke in the video and said that the life safety circuit was being back fed through the neutral when I meant to say that the life safety circuit was completing its path back home through the normal neutral. Voltage was checked from neutral to ground. Be careful folks. Use a meter and check everything.

This is the reason I use my meter for lighting circuits in a commercial setting you never truly know how things are actually wired, thanks for sharing this invaluable information! 😎

I've never heard it called "life safety". I've always heard and referred to it as an emergency lighting circuit, or just simply, emergency lights.

Idk if it's just me. But I swear getting hit by a noodle is way more painful than a hot
2 second fix… you spent more time on the video then actually working and fixing it…

This is exactly why I do not like tic tracers . Not a true reading them . They should not be allowed in the industry. Digital meter only way to go .

sparkdog :
possible guess, but a hot neutral may be an open neutral and yours may be looking for its return path. this is super dangerous, you could be put in series with the load. ckt amps will flow thru YOU.

Always be careful with white wires in light circuits. Many cut corners.

why not just put lights on emergency power instead of some sort of transfer switch. or battery backup. seems risky.

Is life safety just what here in texas we refer to as Emergency Circuits? Here it’s just simply a battery backup. Sorry i could’ve worded this a lot better
