A distribution board is what keeps your electrical system organized and safe. It takes the main power and sends it to different parts of your home, office, or factory. Why EF disconnects? EF distribution class medium-voltage disconnects are robust switches for efficient power. DON'T FREAK OUT JUST YET, THE PICTURE BELOW WILL MAKE A LOT OF SENSE IN A SECOND!
