National Power Mains—Part 1

National Main Outlets Part 1 Judy Nunnikhoven talks about National Main Outlets for North America and Japan. Visit us at interpower.com for more. I don't understand why the world can't agree on one plug pattern. Life would be so much easier. I hear statement all the time, but the fact of the matter is that there are 18 different plug patterns used around the world. In addition to the different plug patterns, there are different voltages and frequencies in different parts of the world. North America, parts of South America and a few other countries run on 60 hertz and most of the rest of the world runs on 50 hertz, however, there are some countries that run on both, such as Japan. While the voltages in most industrialized countries run at 120 or 230 volts, except Japan, which uses 100 volts, voltages can run anywhere from 100 to 250 volts. And, again, some countries use multiple voltages. Cutting off the wrong plug and rewiring the right plug, or using an adapter, does not solve the problem. Once you make a change to the cord, such as rewiring the "right" plug onto the cord, the cord loses it's approvals, which could also affect the approvals on your equipment thumbnail
