Where is 208v used

Cape Verde. Cayman Islands. Central African Republic. Congo, Democratic Republic of. Cook Islands. Costa Rica. Czech Republic. Dominican Republic. East Timor Timor-Leste. El Salvador. Equatorial Guinea. Faeroe Islands. Falkland Islands. Also known as an Edison system, split-phase or center-tapped neutral. This is the most common residential service in North America.

Line 1 to neutral and Line 2 to neutral are used to power volt lighting and plug loads. Line 1 to Line 2 is used to power volt single phase loads such as a water heater, electric range, or air conditioner. Used primarily in industrial facilities to provide power for three-phase motor loads, and in utility power distribution applications. Nominal service voltages of , , , , and higher are typical.

Also known as a high-leg or wild-leg delta system. You are using an out of date browser. It may not display this or other websites correctly. You should upgrade or use an alternative browser. What is the difference between and ? Thread starter watabull Start date Feb 25, Status Not open for further replies. I've been working in the field for nine years, residential new construction and have never dealt with a system.

If there is article on the matter, which one, I can take it from there. If not could someone please explain this for me, thanks. The motivation for this is for two reasons 1 Common knowledge so I will know in the future and don't have to ask silly questions. This question I do not know the answer to.

For more details, search of 'vector addition'; we've gone into great detail on other discussions. In both cases, you have two 'hot' legs that are V from the grounded conductor. In both cases you use a 'single phase' panel that has two 'hot' bus bars, one 'neutral' bus bar and sometimes one 'ground' bus bar. In both cases, only single phase loads are served, either line to neutral loads, or line to line loads. The differences, however are critical. The difference between a v system and a v system is 32v.

Location Alexandria, VA. Watabull: While this graphic is specifically referring to breaker markings, it also illustrates the the most common 3-phase voltage relationships. Location Greensboro, NC. Ok, looking at the ugly's book page 13 it shows just a few of the electrical distribution systems, the common ones.
