Bryan,

Electric meters are dangerous things. I've had a single phase meter explode on me a few years ago, & the only saving graces were my class "0" rubber gloves & leather protectors, nomex uniform & face shield. (wearing face shield was not required & honestly I don't know why I put it on that day..) Thank god for protective gear!!! Also being a lefty I set meters from right side of socket, instead of standing in front of socket.

Do you have any pictures of the meter socket or the meter? Has the meter manufacturer looked at the remains to try to determine what happened. For my single phase explosion, the insulation on the current coils failed & the meter went phase to phase, the meter blew up & the jaws in the socket evaporated ...

A good website for meter men is www.themeterguy.com, they also have have a forum set up to discuss safety, products etc...
