The slot is checked by placing a pin in the slot and indicating the distance between the top of the fixture and the top of the pin as shown in the accompanying figure. Compute distance H to three decimal places by using this formula: H = 1.5 x D - 0.866 x W. All dimensions are in inches.

Answer the following statement(s) true (T) or false (F)
1. A true three-phase transformer contains six separate transformers wound on a single core. 2. The disadvantage for three-phase transformers is that if a single transformer should fail, the entire transformer must be repaired or replaced. 3. Delta connections should be checked for proper polarity after applying power. 4. A voltmeter is a low-impedance device. 5. Three-phase transformer connections are often used to supply single-phase loads, which tend to unbalance the system.
