Wiring an outdoor 220 volt, 50 amp outlet

[dllfo]

All was going well a few minutes ago, then I realized my wires to the 220 box were Red, White, Green...this is good...then a Blue Wire shows up. I think it is the same as a black wire, but I haven't wired anything in awhile.

This is a Midwest U054 Rainproof Power Outlet (right off the box) and I had a spa on this line about ten years ago. We gave the spa to our kids and they cheerfully hauled it off. Having been pretty ill for the last couple of years, I don't go out into the backyard but about once a month, unless I have an oxygen tank with me. And I am on morphine for a torn up back, so I have to be very deliberate and careful when working around high voltage.
I turned the CB off, then locked the box. I hate surprises.

But on the bright side, I used to know all this before the morphine cloud settled in. As I recall, the green wire/bare wire goes to the 12 o'clock spot,
the 3 o'clock and 9 o'clock are red and black and the neutral wire, white goes down at the 6 o'clock position. Except I have a Blue wire. No Green wire. This was installed by a "code electrician" - so I was told.

If you were wiring a 220 line, with a GFCI in it, why use blue instead of green? Unless he was out of green. The wiring is #6, and once it is done,
I doubt my motorhome will pull over 12-15 amps.

We are waiting for a release from the Cardiologist so we can leave town again. So I might as well do something.

After I am through, a friend of mine is an electrician, he said he would take a look at it for no charge. I usually get him at least a case of his favorite beer.

Thanks in advance if anyone has the time to read this.

Must be the morphine... you said "I realized my wires to the 220 box were Red, White, Green...this is good...then a Blue Wire shows up"

Then you said: " Except I have a Blue wire. No Green wire."

Which is it? Red, White, Green, Blue or Red, White, Blue?

I saw that error, went in under edit and then hit save instead of submit. DUH!!

Sorry about that, I have Red, White, Black and Blue. NO GREEN. Again, sorry about that.

It looks like Blue at the top, at 3 o'clock would be black, 6 o'clock is white and 9 o'clock is red.

I am just curious as to whether there is a reason they used blue....such as...blue indicates GFCIs or something.

We bought a big Jacuzzi spa (with a prescription from my doctor) so I got the best and it was great. But I keep wondering if blue is on purpose or if they just ran out of green.

Thanks for your patience.

must be an odd configuration for the wires but european cabling uses those colors. red, black, white, blue and sometimes yellow with a green tracer for the ground. if you have an ohmeter [analog] type set it for RX1 and with the CB off check between a metal ground and the blue wire. full scale means it's continuous and grounded. check between the white and ground also. if the reading is full scale then the white is grounded to the neutral bus as the neutral bus is grounded through the panel jumper or grounding screw. the red and black is safe to assume they come off the CB. the breaker that feeds this outlet, is it a ground fault two pole breaker?

I am confuse, I wrote up an answer, the could not post it. This is what I saw.
I don't understand it...what other URLs???

all that means that if you are a new member you can't post references to url's within your user posting until after you've submitted five postings. its sort of a safety thing with the forum. for instance if I wanted you to go to some other area that would explain your situation I could suggest a site {URL address} and use its address.
