CUC: Turn off main breaker to avoid generator back-feed
The Commonwealth Utilities Corp. is advising all CNMI residents using generators to ensure that their main breaker on their home panel is turned off to prevent any electrical back-feed. This poses a danger to line crew and severe injury and death can result from these incorrectly installed generators.
Do not use generators without the proper electrical switches. All generators should be connected through a double throw switch to protect your property and the line crews working on the system.
Incorrectly connected generators can cause a back-feed through your secondary wiring back to the overhead transformer whereby re-energizing the overhead system to 7,970 volts.
