More often than we’d like, we read of people being shocked while working in churches and on stage.

With all the electronics being installed in churches today, there’s a real possibility of getting shocked or even electrocuted.

Here’s some ways to stay safe around electricity. Also, you’re encouraged to take our survey on if you’ve ever been shocked while on stage, which thus far has generated some very interesting responses.

Church Electrical Safety

1. Test all electrical outlets for proper grounding at least once a year. You can get a simple three-light tester from Radio Shack for $6.00. If an outlet has no ground prong or is improperly wired, call an electrician immediately.
 
2. Install a GFI Breaker (Ground Fault Interrupt) on any electrical outlets near water. This includes baptismal fonts, bathrooms, and outside receptacles. A GFI trips the circuit breaker if any electrical leakage to ground occurs.

3. Never stand in water and touch anything connected to the power line. That includes microphones, lights, guitars and most things connected to sound systems.

4. Wireless mics are completely safe. There’s only a 9-volt battery in them that can’t shock you.

5. Protect wireless mics from being dropped in the baptismal font by putting them in a baggie or covering them in Saran Wrap. There will be a slight loss of fidelity, but they’ll survive being dropped into water. To avoid moisture build-up, remove them from the plastic after the service.
 
6. Never operate any gear with the ground lug (third pin) cut off. Use a smart ground lifter such as an Ebtech Hum X instead of a ground-lift adapter to stop hum.

7. Have your PA system tested with a meter for proper grounding by a qualified electrician. This will assure your microphones are properly grounded.

We hope these tips help to keep you safe. Please feel free to take our survey on if you’ve ever been shocked while on stage, which thus far has generated some very interesting responses.

We had an issue a few months back where one of our occasional vocalists was leading worship. In rehearsal he complained he got shocked when holding his electric guitar strings and his lips contacted the Shure 58. He reported it to be quite a big shock, almost light 110v. He's been around this stuff for awhile so I took his word as true. I dutifully got a volt-ohm meter and tested for voltages. I could not find anything in the 110 volt range, but I did find 47 volts, from the mic case to the guitar strings. Our church building is 2 years old and everything was done properly, but I could not figure out what is was, until I realized his mic had phantom power on from the mix panel in back. One I shut off the phantom power all was well. I did experience the shock myself as part of testing, and it was pretty good, although I think 110 volts would pack a real punch. Not sure why I'd have 48v on the mic case, unless either my pin 2 or 3 is connected to ground at the stage floorbox.

Any suggestions?
