Before the code required the High Leg to be marked Orange it was always marked Blue. I have never seen a High Leg marked Red around here. We have a lot of Open Delta 3 phase services around here.Mark Robison, P.E. » Blog Archive Delta High Leg Can Now ...
One Response to “Delta High Leg Can Now Be the “C” Phase” Grant Register Says: October 7th, 2009 at 10:21 am. NEC 2008 408.3, (E) Phase Arrangement.3 Phase Power Neil Orme
Note that 208 may be computed by multiplying 120 by 1.73, with 1.73 being the square root of 3. For those technicians interested, reference the Pythagorean Theorem from Plane Geometry, and the special case where one leg is half the hypotenuse.Three phase electric power
Three phase electric power is a common method of alternating current electric power generation, transmission, and distribution. It is a type of polyphase system and is the most common method used by electrical grids worldwide to transfer power.240V 3 Phase and 240V Single Phase • OEM Panels
240V power is used in the US and parts of the world. In the US 120 240V 1 Phase 3 Wire is the standard for homes and 240V 3 Phase Open Delta is the standard for small buildings with large loads.Be Careful around 3 phase Electrical Safety & Security Blog

Dual Phase or Split Phase power is also Single Phase because it’s a two wire Alternating Current (AC ) power circuit. In the US, this is the standard household power arrangement with two (Phase A, Phase B) 120V power wires (180 degrees out of phase with one another) like two bicycle pedals and one neutral wire.Table 310.15(B)(2)(a) Derating wire for more than 3 ...
