Thus spake "Scott Granados" <scott@wworks.net>
Is 48V DC at the amps present normallyin switch rooms etc enough to cause electricucian? I have seen bad things with wrenches dropped across batteries even 12 volt car batteries although in this case it was a large battery bank in a submarine but I was curious about the 48V sources in switch rooms.
2500-class devices only need 2A, but a GSR needs 60A -- and 60A DC is significantly more dangerous than 60A AC due to the duty cycle. If you _remember_ to defuse/disable the leads from the A _and_ B fuse panels to the device you're working on, you'll be okay. The real danger is when people are working on the "upstream" side of the power panel, which is often difficult/impossible to defuse and carries significantly higher amperages. S
