I'm not sure why everyone seems to insist on using the (very) old standard of 110/220v, unless situated in a very Rare location, Canada/USA you are most likely going to measure 120/240v. which is the present standard.
Canada, definitely so.
The question of where to measure, is if a modern Dryer is installed, as there will be 4 prong outlet for 120/240/Neut./ground.
Max.

 

Can you see the breakers. I'm assuming

looking for an option that does not require me to open the circuit breaker box.

means that you don't want to open the breaker panel to to expose bare wires. But if you can get to the breakers (necessary if you trip a breaker and need to reset it) you should be able to see at least one breaker, usually at the top, that is a 2-pole breaker. It will be twice as wide as any of the other breakers and that is your main breaker. It will also mean that you likely have 220 volts available.

Unless someone has done something really weird, you probably have 220 volts available.

It’s unfortunate the TS doesn’t have a meter, because I strongly doubt his dryer is 110VAC.

@yourminky, please send a picture of the plug and outlet (two separate pics) for your dryer... Thanks.

 

As stated, all household items are 110volt.

If this is so, presumably whoever wired the original installation did not chose to accommodate any 240v appliance, I would assume.
Your stove is not 240v? Unless you have a gas version.!

USA:
"So, generally since World War II, new homes have been supplied with 120/240 volt electricity, and older homes have mostly been rewired with higher voltage service as well"

Can you show where the TS said he doesn't have a meter?

Gas dryers are typically 120 V. Mine is. Gas stoves can be 120 VAC too for stuff like the timers. The gas furnace is 120 VAC. The AC is 240 VAC,

Oops, made the same mistake as another member! In fact, I think that post helped form my erroneous opinion

So, many members have provided a solution to the TS, without a need to open the main panel. Which is what he asked for.

I still don’t believe his dryer runs on 110V however and would like to see the plugs...

Although....For the last 45yrs up to just recently, my dryer was 120v, but Natural Gas!

The electric meter also should have a ratings label that will indicate the voltage and number of phases.

 

If the place has any AC at all, it should be 220. It might have 120 window units.

Can we assume underground power means modern AC units?

 

Hopefully a little better than neighboring Delhi !

 

If the master breaker is this wide it is 220V.
220V breakers are double wide or are two singles connected together. See red circles.

 

Hello,

I deleted the ai like post with a spamlink.

Why not open the main circuit breaker or fuse panel box?? There is no need to reach inside and measure the voltage, you only need enough light to see inside.
I do offer a note of caution, which is that if the wiring has not been done correctly and inspected then it may not be correct.
I was once asked to do some repairs at a house where the wiring was so seriously incorrect that I would not touch it. Fortunately the cover was already off. I explained the problems to the residents as I was leaving.


In the normal USA residential power connection there are the two hot leads, opposite phase from each other, and the neutral is connected to the separate neutral buss in the panel.

 

Five and a half years on, Hopefully the OP has resolved this ?

 

Time to close
