Electrical Wiring Questions in the U.S.A.


Summary
This is my attempt to clear up some confusion that you may have about home electrical systems here in the USA, compared to other countries, because there is a big difference.

Home Electrical System in the U.S.A. - 120/240volt
Did you know that the Home Electrical System in the U.S.A. is different from other countries?
The typical electrical system for a residential home in the USA is 120/240volt Single Phase, 60 cycle.
For Example: A kitchen wall outlet is typically 120volts.

Home Electrical System in Canada - 120/240volt
The Home Electrical System in Canada is 120/240volt, 60 cycle, which is the same across North America.
For Example: A kitchen wall outlet is typically 120volts.

Home Electrical Systems in Other Countries - 240volt
In other countries the typical home electrical system is 240volt, and the 240volt system is wired completely different than a 240volt circuit found in a home here in the U.S.A.
For Example: A kitchen outlet in other countries is typically 240volts.

Voltage Adapters
This is why voltage adapters must be used when traveling from the U.S.A. into most other countries, and some voltage adapters do not work with large appliances.

Electrical Codes throughout the World
Because of these different types of electrical systems, electrical parts and electrical codes are different as well.
For Example: The color system used to identify specific wires is often very different.

Electrical vs Electronics
Did you know that a Home Electrical Wiring System has nothing to do with Electronics?
The typical electrician who installs electrical wiring for a home in the U.S.A. has received no training in electronics. These are two entirely different subjects. Yes, an electrician may install an electronic dimmer switch or LED light fixture or other similar electrical devices, however the device comes fully assembled from the factory and will not require special servicing by the electrician.
After the home becomes occupied and the residents move in then they will plug in their various electronic devices.

Thank You for Your Understanding
The purpose of this article has been to explain that at this time, I prefer not to deal with home electrical questions from outside the U.S.A. I prefer to focus on the U.S.A. which will produce a much better user experience.
