We helped another sparky rack out some faulty breakers to repair damage caused by rats in an underground substation,and he said we could switch power and load to another row of breakers.He said,gotta use the Star Trek keys to allow the motor driven interlocks to be closed and open,i looked at the keys,they looked pretty ordinary to me,the procedure was,insert the keys,turn to the right and push a red button to open,or green to close,any reson for the odd name?
