I have a service disconnect switch next to my meter base. I recently replaced the meter base and added the service disconnect switch.
Today I pulled the ground wire out of the service disconnect to run it through a conduit to the ground instead of exposed. I got the work done and ran the ground wire back up into the service disconnect. I got the ground wire ready to connect and let go of it to grab my screwdriver to tighten it down. The ground wire fell down onto one of the hot terminals.
The ground wire got red hot and started popping. Eventually the ground wire burned through and a six inch piece fell to the ground. There was still a bit of popping where a short piece of ground wire was welded to the hot terminal so I pulled the meter. Once everything cooled down I discovered the ground wire melted right through the insulation on one of the hot wires. I decided to replace the wire since it was only about three feet long and I had leftover wire.
I was just glad I wasn't holding the wire when this happened.
