1. A branch circuit model of synchronous motors is proposed, which can fully calculate different kind properties of space.

2. The identified terminal of a wiring device shall be connected to the neutral conductor of the branch circuit.

3. Based on the characteristic of circuit diagram in distribution network, some mathematical models are established in order to describe current distribution of branch circuit.

4. The temperature of the test conductors shall not exceed or be able to contact a surface that exceeds the branch circuit conductor rating marked on the luminaire .

5. The rating of an attachment plug assembled to a flexible cord for connection to a branch circuit shall comply with Table 3.2.1.

6. The national code requires that a GFCI be utilized in the branch circuit which supplies electrical power to the aquarium pump and all other electrical aquarium devices.

7. The smoke detection probe controls a relay provided at the driving cap position; the relay controls the power supply of each branch circuit and an electromagnetism automatic valve of the automobile.

8. You must connect this appliance to a properly grounded branch circuit.

9. When the unit is plugged into an AC outlet it automatically self-tests, checks for correct polarity and tests the integrity of the equipment ground, i. e. the green wire in the branch circuit.

10. When an one-point or multi-point earth fault occurs, the monitor can quickly detect the serial number and polarity of the branch circuit earthed, and meantime give alarm to the operator on site.
