Simple plug for 120/240 conversion no splicing

#248211 by benush26 » Mon Apr 23, 2018 7:52 pm

I was wasting time waiting for a prescription and wandered down the RV aisle at WallyWorld and found this

For less than $6, a no muss no fuss solution to running your PowerPro on 120 or 240. I’ve modified an extension cord, but as has been pointed out, plugging in the wrong tools can have disastrous consequences.

This is the Road Power model 09522. Wally World Id per the receipt tape is 002989209522. $5.58

The shop is still too much of a mess to try using the M7, but I’ll just test the plug and turn it on tonight just to see the display again. :D

Hope this helps anyone trying to fabricate an adapter.

Be well,
Ben

Interesting 'workaround'.

Doubt installing a 30A branch is practical.

I am curious which NEMA receptacle the male end fits. NEVER MIND - TT-30

I still question how any adapter to allow plugging a 110 power cord into a 220 circuit/outlet is legal in this country.

It is not.

Now for the hidden detail.

The RV 30A plugs/receptacles are 120V.

Yes I just now looked it up.

So for that 'adapter' to provide 230v, one would have to connect 230v to a 115v 30A receptacle (a definite "NO NO").

Hmmmm. Well JPG, I guess I stick with my cobbled cord. I didn’t bother to look on the package until your postings (I never read burgers since he is the ONLY one I have blocked.). After reading your posts I checked on the package and sure enough it has 1875 Watts max. So much for 240 :( . Oh well, I only lost about $6. Maybe I can dump it at a yard sale.

Thanks again JPG! Saved my butt once again!

Be well,
Ben

1875W

That is because the output(female) receptacle is rated at 125V 15A.

When I was first thinking how can I plug in my Shopsmith with a DVR motor, even before I installed the upgrade, the RV adapters came to mind. I didn't want to cut off the plug to change it but wanted to be able to go between 110 and 220 volts. I have a cord, the one below, that plugs into a 220 V 50 A outlet and has the 30A female end. The female 30 A end is 110 V and the cord simply doesn't use the second "Hot" wire needed to be 220 V. This adapter works great for my RV when needed but will not work for my Shopsmith. I ended up buying a heavy duty short 110 V cord with the standard female plug on one end I put a 220 V male plug on the other end to match the 220 V outlet in my garage. Making an adapter cord seems to be the only way to get one and the plus is the normal 220 V end added to the cord can be any to match the outlet you have. Of course this violates the Electrical Codes.

Does the PowerPro actually use 220vac simply brought to it by using the hot and neutral wires (thus making it non-compliant with NEMA)?

Is a PowerPro that has been built to operate on 220 vac considered to be compliant? If so, HOW SO?

I am assuming that a standard 110 vac NEMA compliant power cord is used for 110 vac operation.?

John - What is there about plugging the PowerPro into a 220vac power outlet that makes it illegal. Isn't the DVR designed to work on 220vac.

I understand that making a pigtail connector that appears to be 110vac but actually carries 220vac is scary and maybe that is what you are referring to.

What is the NEMA 6-15P?

220V 15A plug - tandam blade(115v/15A is parallel blade)

i.e. narrow side of blades face each other rather than the wide sides facing.

What makes a 'pigtail adapter' "illegal" is the receptacle end becomes capable of delivering 220V to a 115v appliance.(220v into a 115v plug)

As far as "legality", that may be a misnomer. Code violation more precisely. For all intents equivalent.

I do agree that a power cord with a white neutral wire being used on a 220v appliance is questionable from a code perspective.
