I just noticed in my RV's generator booklet it states the generac will:
1-run a 1.5 HP sub at 2800watts(per hr i assume)= 47 watts perminute wpm x 16 min= 752 w used in 16 min
2-run a 1/2 hp sub at 1500 wph "........................=25 wpm x 30 min = 750 watts used in 30 min
My old pump is #1 and my new is #3
With the run times Ive given ,they work out the same in KWH used.
So is this an accurate estimate and how its done?
If they are near enough the same what are you getting with the 1.5 hp motor you dont get with the .5 hp one?
1. faster discharge rate
2.more robust innrds? anything else?
