Another 200a Oval power cord replacement question

[jankdc]

Hi, I really appreciate this forum. I have a 200a and I seem to have lost my oval power cord.  I'm trying to decide whether to find an affordable replacement vs replacing with an iec. First question, I think that I can find a cord locally, but there are two types of 163 connectors. Facing the plug, would the line be on the right and the neutral be on the left or the other way around? To read more on the HP/17952 vs UL/17280 power cords you can go here. 

If I decide on replacing the inlet with an IEC connector, are there any tutorials or videos on how to do it? I assume it's pretty straight forward, but I prefer to read up before attempting something new.

Thanks!

Even if you get a replacement cord that is the opposite, you can always change the pins around on the molex connector inside the piano on the amp rail to match.  Need the right tools to form an IEC port out of the oval one.

If I'm going to do that amount of work, I might as well do the IEC port. You don't know which side is hot?

Thanks,

You can look inside. The black wire is the hot wire. My GUESS is that it is the one on the left, but that's just a GUESS based on the hot wire being on the right in an outlet. (why would they cross the wires?)

A lot of us don't have 200's that are that old so memorizing which one is which isn't really a priority.

Have a multimeter? Either side could be hot, I wouldn't assume. If you are replacing it, the back of the IEC receptacle should have an "L" and an "N" for Load and Neutral.

I only had a file at hand so I used it to file out the hole to fit an IEC plug. It worked and it ended up looking good, but it took me like 2 hours

Cinnanon, how would a meter tell you which side is hot from the outside with no power?

Looking inside to see which wire is black (hot) would be the only way
I could think of.

Right, I was going to tell him to use the multimeter to determine how the current or new power cable is wired.

[pianotuner steveo]

A new power cable should be polarized... The wide plug is the neutral.

Btw, for those of you that don't know- the neutral wire and the ground wire actually connect to the same place in your breaker panel!

Well it turns out it's a 200, not a 200a. : )

The good news is that I found the cord for it and I have it playing. I tested the cord to see what side had the power:

What I found is that in this position, with the center pin hole (earth) at the bottom, the live (power) is on the right:



Which would make the power side of  the receptacle the left pin:


This would make the type of cord a 17952 and compatible with old hp products according to this site.

You are right. Here is a picture on the inside:

Cool. I actually know more about house wiring than electronics. I thought that would be the case.

So just to clarify if I can- If I put in an IEC receptacle and just wire it in the same order as it is currently wired, (as you face the back of the piano) Black to the left, Green center, and White on the right, I should be ok, yes?

This thread has been dormant for nearly 8 years, and the member who first posted hasn't logged in for over 3 years! I'm not a forum mod, but I believe you were correct to start a new thread with your question about wiring for IEC conversion.

Anyway, don't assume that *any* existing wiring is correct. "Assumption is the mother of all..." See my reply on the other thread, please don't reply here.
