In an electrical system, what is the white wire? - CORRECT ANSWER✔✔- Neutral
How many wires would you run from the controller, if you have six-station sprinkler system?
- CORRECT ANSWER✔✔- 6+1 common
The voltage in low-voltage garden light is: - CORRECT ANSWER✔✔- 12V
In a low voltage system, there are two 25 watt lights, five 30 watt lights, and one 50 watt
light. How many watts would you have to run in the system? - CORRECT ANSWER✔✔-
250. To determine wattage, just add the watts.
How is the wire size in a low voltage system determine? - CORRECT ANSWER✔✔- the
distance to be run (to compensate for voltage drop, caused by a long run of wire)
An outlet must be... feet from the pool. - CORRECT ANSWER✔✔- 10 feet
If a wire is #12, what is the maximum length for one set of landscape lights? - CORRECT
ANSWER✔✔- 100. Measured from the transformer to the last light.
One of the following wires gets the hottest: - CORRECT ANSWER✔✔- #12 series ( the
greater the resistance, the hotter the circuit gets. #12 is smaller than #10, so it has more
resistance. Parallel circuits have only a fraction the resistance as one in series)
What causes lights to dim at the end of the line? - CORRECT ANSWER✔✔- They were
wired in a series (if wired in series, each light further from the source has a drop in voltage
equal to the amount of voltage used by the previous light. Also not enough amps in the
system.
, If you are coming off a 120V household circuit and you must convert to 12V, you should: -

shock? - CORRECT ANSWER✔✔- GFI (GFI means ground fault interrupter. The circuit
breaker and fuse protect the circuit. GFI protects you. It is much faster and responds to a
much weaker electrical event.

conductors of American wire gauge size #12. They must be copper, not aluminum.)
A... light bulb gives off the truest color. - CORRECT ANSWER✔✔- quartz halogen
You use a... to pull a wire through a conduit. - CORRECT ANSWER✔✔- fish tape
What is the maximum voltage you can work with before you must obtain a building permit? -
CORRECT ANSWER✔✔- 12V
What is the white wire in a sprinkler system? - CORRECT ANSWER✔✔- neutral
