Main Fuse-Panel Emergency Light - The area around the Main Electrical Panel is
usual pretty dark, especially if it is located in the basement. That's during
daylight hours. At night everything is dark during a powerfailure, or tripped
circuit breaker, fuse, etc. This circuit provides ample time to fix the
problem.....(Tony van Roon's diagram added 08/09) |
