Anyone running an extension cord for a Masterblaster?

Reason I ask is because when I run one I notice a good difference in power. I know most cords only support up to 15 amps. I need 18 to run it at full power per say.

This is the only cord that seams to be able to support 20 amps.

Anyone else running cords? cheaper possibly :cool:
 
I use a 12 AWG cord. Despite the 15A cord set rating (because of the connectors), it can run 20A over 50 ft.
 
Al is exactly spot on !

Been running 12AWG extension cords for years with the Master Blaster and never had an issue.. I run this set up off of a 20Amp Circuit breaker at the Panel, using 12AWG Romex wire, connected to a 20Amp receptacle I installed..

Have not noticed an issue with this set up...

Exactly how long are you going to be running the Master Blaster ? I run mine long enough to go all the way around a vehicle, top, engine compartment, (because it was pressure washed before the vehicle was washed), all body panels, seams, lettering, etc., and have no problems.

That price seems right. You could go through the trouble of making your own from 8 AWG wire from eBay, McMaster-Carr, Grainger. Add the plugs. You'd come out better getting the ready-made one.

Don't take offense to this, but, are you plugging into a 20A outlet?
 
I'm only running 25ft max, I honestly wanted a 15ft but couldn't find one. I bought a 12 gauge 25ft rigid cord from hd an i definitely felt the power loss. All the 10/3 gauges are too long and will most likely cause loss. Do you have a link to the one ya got? :)

I am running a 20 amp circuit off my main.

The wire would be warm in that case. 12 AWG is only rated for about 10 amps for transmission of power for any length of time, but can handle a few times that before getting hot to the touch.

Cut it and make your own!

You think there wouldn't be loss? I ran the 50 ft an returned it. You think by cutting it to 15 ft it would be ok.
 
Sorry I wasn't clear, I was running a 10/3 at 50 not 8. That's why I posted, to see if the 8 was enough.

For regular use like a MB, it is more than 20 amps like used in house wiring. In house with a 20 A circuit, the code requires 12AWG. The 10A is for power transmission but this is not considered a power transmission application.
 
Driver,

If you said you are getting a difference in power, did you measure the voltage and see how much it dropped when you turned on the Master Blaster ?

I dont get why there is a need for that bigger thicker 8AWG or 10AWG wire to run this tool...

Those big wired extensions for Welding - well, that is a totally different application that has to be a huge power hog compared to the the little Master Blaster with 2 motors...

"""The wire would be warm in that case. 12 AWG is only rated for about 10 amps for transmission of power for any length of time, but can handle a few times that before getting hot to the touch."""

I think I unplugged it once after using it for a long time on a big SUV and the connection from the Master Blaster to the 12AWG extension cord was a little warm but not hot to the touch...

Just thinking out loud...
Good luck !

It's the fact I couldn't find a 10awg in 25 or less. If I run a 50 I'll lose juice over the distance. The 8awg might be a bit overkill but I know it will run fine an cool. Plus even if they offered an 8 in 50 there's no ways I'd need that much.
 
One other variable is the distance from the breakbox to the outlet. For example, if you breaker box is 50 plus feet from the outlet you are using and downsteam of other outlets you could already have a lot of drop in the line. I would get a voltmeter and measure it.

The ideal 20A circuit is a dedicated line from breaker with one outlet and as close as possible. Also, check connections in breaker to make sure no strange stuff (two circuits tied, etc).

My box is in my garage so a short run to the outlet.
 
I had to have a special outlet put into the garage to be able to run both motors on the 4hp unit. I do use about a 15 foot chord that it HD, will get the spec if its listed. it was a Heavy Duty chord.
