At some point we have all been asked or will be asked to cut the electric , when it is necessary, from anything from a structure fire to water endangering electric, just to name a few. When was the last time you thought of how you were going to shut that panel down correctly? The power companies frown on pulling meters or cutting loops and this may not completely accomplish this task, depending on many factors, feel free to add your own.
Correctly shutting a panel box down is really easy, by throwing the main breaker, right? Wrong! Correctly shutting this panel down is easy, but throwing the main breaker is not the answer, if you want to be sure an avoid an arc.
When shutting a panel box down, whether breakers or fuses, goes as follows: Turn off all of the individual breakers, or take out the fuses, then trip the main breaker or pull the main fuses. Practice this in gloves, not as easy as it sounds.
To restore power, do this drill in reverse order, however, I’m not sure how many of us are tasked with the restoration of power, doesn’t happen in the Midwest.
