Funny thing we have noticed with our dust collectors. one is 75hp, 480v, full voltage starter. The other is 60 hp, 480v with a soft starter. Both come from the same panel using 100 amp breakers. That panel is fed from MDP 250amp breaker. When these are running they only actually draw about 45-60 amps depending on filter condition.
In warmer weather we had been starting the 75hp (full volt) first, then the soft start 60hp. Now that it is cold, the full volt starter trips the 250a breaker in the MDP. We kinda figured cold grease or whatever.
So we started the soft starter first and then tried starting the full volt. Came up no problem. This confuses me. I figured that would only add more load to the MDP breaker... so why does it seem to help starting the full voltage collector?
Just curious if anyone has an explanation? :?
