I have 2 comps a 3 and a 5 and all the tanks plus 25 gallon receiver/Franz. I leave the breaker to the 5 off and the extra 120 gallons I have on line plus itself gives the 3 some real legs. I can time it so I can DA near continuous with about 1 five minute break from 3 hp and am really done with most jobs before I run low. I run 1 smaller motor longer, reduce the starts and reduce the peak a bit using 3 hp vs 5.
Flip a switch and the blue comp would pump on the line, its tank is working all the time.
When I did leave it on I had the adjustment set so unless demand was hi the secondary came on, never in normal use. I used it for a couple weeks last year a bit for outage and once for sandblast, 99.95% of the time its just another air receiver.
