220v Plugs

[Rollie Meyers]

It depends on what country you are in. In the US, we do not have this 220 volt receptacle. This however is a common receptacle across the pond. In the US, our wires are for example, 12/2, which really is a 3 wire cable, but classified a /2 for the non-ground wire. The extra wire is an unsheathed and only used for ground, therefore not part of the wire set used to carry voltage.

My point is that 220 volts went away before before WWII in the USA, Cuba, and China, are a couple of countries that do still use 220V.

In all my 79 years it has been 110 and 220 volts.

110 volts and 120 volts A/C are really the same thing, just expressed differently.

The actual peak voltage of a wall circuit is 170V A/C.
110V is the average voltage.
120V is the RMS voltage.

It's the same thing, just expressed differently because it's based on values measured and derived from different points along the sine wave.

Today, nearly everything in the USA uses the RMS figure.

Only verbally, my friend. That's the conundrum in these conversations what folks say and what actually flows through the wires isn't always the same. Habits die hard for sure.

Here's an article that deals with 110/120V.

If the peak-to-peak voltage is 340V, and the amplitude is 170V, then the average is 0V, not 110V.

[andy bessette]

It is only 0-volts for the briefest moment.

[Rich Engelhardt]

If the peak-to-peak voltage is 340V, and the amplitude is 170V, then the average is 0V, not 110V.

True but - that isn't what is meant buy average voltage.
I only used that article because it's simple and to the point.

This one gets into more detail and goes into why they only use half the wave:

This is also well beyond the scope of the OP so - I'm dropping it.

Same as people refering to a half ton pickup truck. The makers stopped using that term in the 1930's

Motor Trend article from 2021 used this term: https://www.motortrend.com/features/...lf-ton-trucks/. I supposed it should be class 1 ... class n not based on ton ratings. So MT is keeping the term going.

The new(11 year old) ford ranger half ton is 1,600 pounds. I think the one ton is over 3,000 pounds so roughly 50% off.
