We have a used 220 3 phase charger for our electric lift truck, have had it about a year. We use the lift very occasionally and only need to charge it about once a month or 6 weeks. We turn the disconnect off to the charger when it's not in use to avoid the constant buzz it produces. When we turn the breaker on (charger not connected to the lift truck at this point) it blows a fuse about 1/3 the time. We had it checked by the manufacturer of the charging unit, they found nothing wrong and their advice " These are built to be left on and used every day, just leave it on". I hate the stupid buzz. Any other options?
