This is the craziest thing I've seen in a long time. Why would anyone do this!! Every breaker is tied to the one next to it???????

Can't answer why. Those are not approved handle ties tho.

"Could be" ... multiwire circuits? Or 240 volt circuits? Or ... ?

Regardless, though, as Jim said "Those are not approved handle ties tho."

Thanks, forgot to say it's in a 1999 1701sqft log cabin.

Do they make 220 volt grow-lights? ;-)

Only outside North America, 220V does not exist in the US.

BTW 110,220 is DIY lingo.:D

Nominally that's true, but in practice voltage fluctuates all over the place depending on numerous factors. One power conditioner I installed has voltage meters that record minimum and maximum voltage over a 24hr period. I regularly saw minimums under 210V and maximums over 260V on the nominal "240V" service. Hence the power conditioner...

(RMS voltage was typically around 230V under normal demand.)

In my area in NC the power company is allowed 10% either way so if the exact voltage advertised is 240 volts......216 to 264 is acceptable to the power company if you have a voltage complaint.....so if you say any number between 216 and 264 you will be correct.

"so if you say any number between 216 and 264 you will be correct"

Incorrect.

The specified voltage is what the variation is allowed to be around, i.e., 120 volts / 240 volts.

If one happened to measure the voltage as 117.3 volts / 234.6 volts, one would look like an idiot referring to that as "117.3 volts / 234.6 volts". The voltage would be 120 volts / 240 volts, or simply 120/240 volts.
