In the early/ mid 1950's, voltage here was 110/220.
Almost all homes had 2 wire 110.
Do not remember any wired for 110/220.
Easy to tell - see a 2 wire drop, it was 110.
Mid 1960's, 115/230. New homes wired for 115/230. People started getting central air installed.
1970's 117/235.
Voltage at my panel right now 120/240.

I worked as an electrician in a mill in late 1960's. 3 phase was 440. By 1980's, a lot of the 3 phase was 460.

My Sept 1955 Fairbanks-Morse Onan V45 is labeled 115 volts.

November 1966 JC labeled 120/240.

I don't have anything older I can get to at the moment.

BTW The 110 came from Edison. He started with gas light he wanted to replace. He figured that it would take 100 watts to replace that light. He then decided that he would like the current to be 1 amp per bulb. 100 watts at 1 amp is 100 volts. He then added 10% or 10 volts for line loss and we got the 110 volt standard. The early distribution on the street was three wire DC -110, Common, and +110 Each home got just 110.

He designed and developed the whole system. generators, distribution, Fuses, house wiring, switches, sockets, and the light bulb.

He didn't imagine home electricity being used for any thing but lighting, so there were no outlets. Just sockets. And of coarse we all know he went with DC not AC.

Only God gets everything right.

From another forum.
I did some research on this a while back. As you mention, 110v was a historical maximum: 100V + 10% allowable, which was revised in 1954 (ANSI C84) to the current US voltage standard of 120v +/- 5%. Plugs and receptacles are often rated at 125V/250V, which allows for the high side of the allowable range - i.e. the maximum allowable voltage, not the nominal. Other oddball voltages like 115 or 117 volts often appear on motors, and this was to indicate the expected voltage at the motor - 120V minus a few volts for distribution wiring.

[/COLOR]BTW Just for fun I checked some manuals and advertising for Kohler light plants (Generator)
1920 - 110
1926 - 110
1924 - 110
1228 - 110
1937 - 115
1941 - 115
1945 - 115
1947 - 115

I have a 1947 It is rated at 115 Volt, A C I am going to readjust it for 120. I take it to engine shows and use it to make coffee and waffles in the morning so the faster cook time will be welcome. (Grin) BTW The waffle iron is marked 110 V and is around 1920. No I am not serious about worrying about this

Frank- would hate to see you burn out your waffle iron. 120 volts will dissipate 19% more heat than 110 volts. Might make it heat less evenly as well.

You can joke all you want but when you have people standing around waiting for coffee things can get tense I am lucky the generator is automatic start.

BTW we always get smiles when people walk by and see the generator running but the lights are off, and I explain that we are cooking our meal.

That sounds like a lot of fun! So, the generator will start and stop as the thermostat in the waffle iron cycles. Or do you leave some other load on at the same time in order to avoid that?

I want to use mine for back up power here at the house. Would be fun to hear it start up and shut down in the middle of night whenever the refrigerator runs.

110, 115, 120, 125 volts. In the real world it *really* doesn't matter to anything that may be on line. It's not hyper critical in other words. 120 volt bulbs would have shorter lives on 125 volts...

Thermostat? These are period correct appliances. We ain't got no stinking thermostat.

The appliance that gets the most use is a antique broiler.


We cook sausage with pepper and onions, Corn on the cob, bagels, Toast, You name it.

I have used the light plant to run the frig during a ice storm. It was comforting to hear it start during the night. BTW The adds from the time push that Mom can have a "City Refrigerator and a well pump. They go on to explain that a well pump means a indoor bathroom.

Very cool. What is the model and brand of your broiler?

I've been wanting something like that- essentially an early toaster oven- for a long time. But don't know what to search for.

Even the early waffle irons seem to have thermostats (non - adjustable) to regulate the temperature of the cooking surface. The old coffee percolators have them too. I have a little one that that is 1 kW! It makes coffee in a HURRY, then switches to a small "keep warm" element. It's an oldie, all chrome and nice cloth cord.

Wife and I joke that between it being so fancy and it's size really only for one person, that it would look perfect on some exec's desk 100 years ago.

We're loosing the thread though. To be clear, ALL of the appliances we're talking about will undoubtedly be rated for 110 volt.

I particularly like to collect appliances that are specifically rated for AC or DC as well. Curiously, it seems that nearly ALL DC generators state 115 volts (6, 12, 15, 32, 40 volters etc not withstanding), even when they're clearly from the "110 volt era". So there's another interesting wrinkle...

I have the one shown but I usually use a antique farberware It is also round with the coils in a lift off cover.
here are a couple simular ones
