220v 10-4 Extension cord round locking to angle plug

Background:

I recently purchased an espresso concession van and am starting a weekly event on May 10th. They have assigned me a spot and my electrical power comes from a 4 prong angle outlet. My current cords and plug ins are 30 amp 4 prong round locking outlets.

I went to home depot and bought a male angle plug (30amp), 4 feet of 10-4 and a female round locking plug. The female plug was easy to wire as it is well colored with green, brass, brass and silver. I attached the red and black wires to the brass terminal screws, the white wire to its silver terminal and the green wire to the green terminal

Question: The angle plug was not as well marked. The green was well marked at the 12 oclock position, but the other 3 were difficult to tell if colored or not and that is my problem.

It appeared the correct pattern starting at 12 oclock and moving clockwise was Green (12:00) Red (3:00) Black (6:00) White (9:00) (This is facing the back of the plug/wiring area with the plug in bars facing downward and not visible). The red and black appeared to be brass colored terminals, but the white connection may have been brass colored as well as it was too faint to really distinguish.

I felt pretty sure I connected it correctly, but was reading on some other wiring info on the net and saw a 220v dryer diagram with a different pattern. It had Green, Red, White, Black (clockwise again) for a breaker panel box, which may be different, but I am no expert so wanted to know if anyone can let me know the correct config on the plug.

Hope this makes sense, appreciate the help.

You have it wired wrong. 6:00 should be neutral (white).

3:00 and 9:00 should be the hots (black and red)

The plug should come with a sheet, and have X,Y,N, and Gnd markings.

Take a look at these two.....They may help..

As mentioned, X,Y,W,and G are used to identify terminals.

X+Y are hot , W is Neutral, And G is ground.

There should be two terminals marked X Y. Those are the hot(black, red) wires.

Changed the white and black

Thank you all so much, I really appreciate it. I have now changed the white and black wire. I've included pics of the current configuration below to make sure its right.

Here is the angle plug:




Here is the other end:







Is this correct now?

Here are pics since they didn't show up here for some reason:

Yep they are correct but however you may run into one issue allready the straght blade you got that one is rated for 50 amp and the twistlock you got is rated for 30 amp and IMO it not a really wise mix there unless you have 30 amp stright blade plug [ the same one you will see in 4 wire dryer cord is ] then it will be fine.


Merci,Marc

On the directions in the box it says for use as a 50A or 30A, but then it shows an L shaped neutral plug should be used for the 30A (in a diagram that I missed). The power I am plugging into only has the straight blade hole if I remember correctly. Should I find a different angle plug that is only rated 30A with only a straight neutral plug, or is that even possible? I'll go check the power source again and if its possible to use the L shaped neutral I'll switch if if I can find an L shaped plug (not in box).

Thank you very much! Saved me a lot of problems I'm sure!

for the 14-30 R the netural blade will be L shaped and some plug in devices some of them carry both straght [ 50 amp ] and L shaped [ 30 amp ] so you may swap it over.

for some reason you can't for that one you can buy new one for few bucks many place will stock this item.

just recheck your power supply to verify if that is 30 or 50 amp repectale you plan to hook up.

Merci,Marc

It is not a different plug, but the fact you have a 40 or 50A source, with a 30A cable. By rights, you should have an 8/4 or 6/4 cord to your trailer's panelbox.
