Electrical – Does this 3 prong 250V outlet in the Philippines have two hots and a neutral or hot/neutral/ground


The plug claims to be 12A 250V, so I think its a NEMA 6-15R or 6-30R which handle 15 or 30 volts respectively.

Here is a picture of the outlet:

The Philippines have two systems at once. Keep in mind they were part of the United States for a long time (as a result of the Spanish-American War). Part of the country (i.e. in the old American military bases and cities where the US did the wiring) is done to the North American 120/240 split phase system. The newer, indigenously wired sections are largely being done to European/Asian 230V spec, although with 60Hz power so they can sync generators.

The Philippines generally use North American receptacle standards, wire gauges, boxes, etc. -- even in the Euro-style areas. They tend to follow NEC more so than Euro standards, modified for the 230V single-leg service.

They also have an appalling tendency to put 230V on American 120V receptacles (NEMA 5-15). You really have to watch what you plug in!

What you're seeing there is the right thing being done -- a NEMA 6-15 230V socket being wired with the correct North American plug. If you are in the 120/240 American-style cities, that will be 240V hot-hot-ground, with each hot 120V from ground. If you are in the rest of the country, it will be single-leg 230V hot-neutral-ground, with one pin near ground and the other 230V from it. Except for certain places where it will also be hot-hot-ground, with neither one anywhere ground.

When I say "230V" I mean 220-240V. When I say "120V" I mean 110-120V.
