how many watts generator (min) would be required to run the master blaster? of course if generator can handle the mb it should be able to handle a rotary, da, vac. not all at once . I would like to get a small quiet generator for this function. and lightweight enough for in/out of a pickup.
 
my understanding , while I'm not a electrician. volts x amps = watts . so 120 x 19 = 2280 watts . assuming this is max startup draw with with both fans at same time . if u can get by starting each motor separately say 5 seconds apart on a 15amp circuit breaker and be ok , must be a lower running amp then the 2280 ? so maybe a 2000watt generator will do it ? a nice little Honda . anyone know ?

My master blaster will blow a 15 amp breaker after about 2 minutes.

I would get something that is a bit over your calculated 2280 watts, and has a decent 'surge' power rating for when the motors first kick on.

I'll see if I can hook up my watt meter to my Master Blaster and give you my observation.

While Bill is completing his check on his MB...

As a starting point I always:
-Figure in an additional 70% at start-up...Which would be around a total of 3876 watts, max., for those initial M.B. start-ups.

-Here's one that may be in the ballpark:


Generac GP3250 Portable gas power Generator. Contractors Direct.

I was looking at them smaller inverter generators , Honda-yamaha . small , quieter ? but too pricey . that generac was my next option . if I have trouble with my breaker flipping is it simple as just putting a 20 amp breaker in? do I then need min of 12-2 or will 14-2 wire do ? gosh I'll be dang pissed if I can't even use my mb .

For my residence...

-Table 310.16 of the NEC requires, to be code-compliant in my County, 12-3 w/ground (for this type of MB load service)...Using no more than a 20 amp breaker on a circuit. I suggest to also use a GFCI duplex for that circuit as well, if you decide to go that route. Your Local NEC may vary.

-No need to "upgrade" the Generac generator pictured/listed above. [Plug'n'play your MB there. :)]

Yes...The MB is a powerful unit, in more ways than one!!

bob , do u work for NASA or something ? u have extremely knowledgeable answers on a lot of subjects .

what would be your take on a power inverter ? one that hooks to car battery .

I have my mb already , been working all weekend havnt had the time to even try it out yet to even see if I have any problems .

-I would say a generator, such as the Generac, along with a $50-60 "Battery Tender" would be the least costly proposition than an invertor...I sure wouldn't want the high initial cost of the invertor, coupled with fuel-expenses, just to have a battery-charger!

BTW: Speaking of the MB being a 'powerful-unit (electrical usage, in this case)...

-The MB uses almost the same amount of electrical current ($$$), upon start-up and then be on: continuous-run cycle, as it does for these household items to do the same:

Item ; then: Watts

-Lamps (2 60 Watt bulbs)=120
-TV (color) =115
-Radio = 75
-Refrigerator 425+
start up current(+70%) = 715
-Microwave =650
-Gas furnace/blower
1/8 HP 300+
start up current (+70%)=510
-----
2185 Watts




Quite a: Big electrical "draw", the MB doth have!

im thrilled ! my mb ran just fine off 15amp circuit . started each motor separately . when I did receive the mb and i must say it is from what I thought it would be - its smaller , lighter , quieter. no problem with hose blowing off as some have stated. this baby has some power . if u don't hold onto the hose it almost flops around like a loose fire hose . I did get a 10' extension hose as I need to get up 7' + high comfortably . as well as a wall hanger just to keep stored out of the way . I will still get a generator for a many of use purposes. bye bye leaf blower .
