WIRING DIAGRAM FOR 208 V UNBALANCED 3 PHASE
TECHNICAL SERVICE BULLETIN - Stiebel Eltron USA
Wiring Tempra® and Tempra® Plus in a 208 V, 3-Phase Environment This procedure explains how to wire Tempra® models for 208 V 3-phase. Tempra® 12/12 Plus, 15/15 Plus, 20/20 Plus, 24/24 Plus will be unbalanced 3-phase. Tempra® 29/29 Plus & 36/36 Plus will be balanced 3-phase. Stiebel Eltron Tempra® units are designed
208V Single Phase and 208V 3 Phase • OEM Panels
208V 3 Phase power also goes by the names 208V 3 Phase 4 Wire and 208Y/120V. These are technically more accurate because they refer to the neutral. The “4 Wire” in 208V 3 Phase 4 Wire refers to the neutral as 4th wire. The” Y” in 208Y/120V refers
Hardwiring to 120v, 208v, and 240v loads from a 208v/240v
Smart-UPS RT units designed for 208v/240v environments have unbalanced 3 wire outputs and require a transformer to supply 120v loads. Resolution: The 208V/240V Smart-UPS RT is a single phase UPS with a 3 wire unbalanced output. They require 2 hots and a ground on the input, and 2 hots and a ground on the output. For detailed wiring

How can 208 be single phase - Answers
A 208 v three-phase system has 120 v between each live wire and the neutral. It is used in the USA as an alternative to the 120/240 v single-phase system, offering 50% more power for the same current.
when does the neutral wire in a 3 phase system carry voltage?
when does the neutral wire in a 3 phase system carry voltage? Ask Question but maybe its not clicking in my head.. when does the neutral line in a 3 phase system carry voltage. i do understand the answer is quite simple (When the legs are unbalanced) but for whatever reason, its not making sense to me. (star). As shown in the diagram
Three-phase electric power - Wikipedia
Since √ 3 ≈ 1, defining V LN as 100% gives V LL ≈ 100% × 1 = 173%. If V LL was set as 100%, then V LN ≈ 57.7%. Unbalanced loads. When the currents on the three live wires of a three-phase system are not equal or are not at an exact 120° phase angle, the power loss is greater than for a perfectly balanced system.
How to wire a 208 volt 1 phase? | Yahoo Answers
Nov 11, 2009I purchased a Wells G19 Electric Griddle. In the wiring diagram it included how to wire it 1 phase. The unit will be ran on a generator and it will only run one phase. The wiring diagram shows how the unit should be wired but not how to wire the wires coming in. So I am lost and not sure what to do. The plug is three prong standard 220 plug.
