Wurlitzer 200 Wiring for replacement IEC Power receptacle

Hi, I want to replace the standard power receptacle with a three prong IEC receptacle. Does anyone know how I would wire that? There are three wires- Black, white and green. Would it be the green that would go to the ground pin? and if so does it then matter which of the two "flat" pins the black and white go to? Thank you!

Sorry to confuse matters- all three are "flat". But the green would then go to the higher one in the centre?

First, if you don't know what you're doing with electrical wiring, don't mess with it. Especially when it comes to mains voltages. You could injure or kill yourself or someone else, or you could start a fire, or all three.

If you have to ask if green is ground, then you have some homework to do, and you should ask for assistance from someone with experience.

But for the sake of providing some useful reference info, which readers would do well to independently confirm instead of relying on a forum post:

Black (US standard) or Brown (int'l standard) is hot or "line"
White (US) or Blue (int'l) is neutral
Green (US) or Green w/ Yellow Stripe (int'l) is earth ground

Wurlitzer EPs with what appears to be original wiring most likely adhere to US standard, but you can't be certain, since they are all old at this point and may have been altered since originally manufactured.

IEC 320 C14 receptacles (aka "power inlet") are often labeled with L, N, and ⏚, which correspond to the conductors noted above, but may not always be labeled.

Attached is a C14 pinout diagram as seen from the normally-visible side. Of course, the terminals on the other side will be mirrored from this view.

Note also that the original oval-type power inlet is lower-profile than a typical C14 inlet, and the wooden case may need to be modified to fit the substitute component, either in the original location or somewhere else.

Absolutely! I hope I didn't come across as too harsh, or judgmental of your capabilities. I just feel it's better to strongly advise caution on this subject, rather than encouraging folks to jump in head-first when the consequences are potentially lethal.

With some basic instruction and guidance from an experienced mentor, you can absolutely gain the knowledge, techniques and skills necessary to safely work with hazardous voltages.
