◉ What are considered low-voltage gloves? Answer: Class 00 or 0
◉ What class of gloves would you use for 15K volts AC? Answer:
Class 2
◉ Before use, every glove should be? Answer: Field tested
◉ The first thing that can lead to a legal issue when working on the
roadway? Answer: Improper traffic control
◉ High traffic area? Answer: Arterials streets and multiple lanes of
travel
◉ Low traffic areas? Answer: Collect streets, typically, narrow and
single lanes of travel
◉ OSHA mandates that you must maintain a minimum of how many
feet clearance from overhead powerlines? Answer: 10ft
,◉ What is an electrical explosion with a tremendous amount of
pressure and heat? Answer: Arc flash
◉ What must you do before you dig? Answer: Call digalert
◉ Electricity flowing through wires is similar to? Answer: Water
flowing through a pipe
◉ What is ohms law? Answer: E=IXR
◉ What is E in Ohms law? Answer: Voltage and it's is measured in
volts
◉ What is I in Ohms law? Answer: Current and it measured in amps
◉ What is R in Ohms law? Answer: Resistance and it's measured in
ohms
◉ If electricity is like water flowing through a pipe voltage is like?
Answer: Water pressure
,◉ Current is like? Answer: The amount of water flowing through a
pipe
◉ Resistance is like? Answer: The size of the pipe
◉ Power is like? Answer: The amount of energy consumed
◉ Rules for series circuits? Answer: Current is constant, voltage
drops across each load, resistance add up from each load, power
adds up from all the loads
◉ Rules for parallel circuits? Answer: Voltage is constant, current
adds up from each branch, resistance reciprocate from all the loads,
power adds up from all the loads
◉ Rules from combination circuits? Answer: Series rules for the
series load and parallel rules for parallel loads
◉ What is bonding? Answer: Connecting conductive objects together
by means of all conductors so they are at the same potential
◉ What is grounding? Answer: Connecting a conductor or electrical
device to the Earth
, ◉ What is a traffic signal warrant? Answer: A condition that an
intersection must meet to justify a signal installation
◉ What is a signal phase? Answer: A group of controller, timing
intervals, and setting used to control one movement of traffic at a
signalize intersection
◉ What traffic movements are even phases? Answer: Thru
movement
◉ What traffic movements are odd Phases? Answer: Left term
movements
◉ What is a ring? Answer: Two or more sequentially time conflicting
phases
◉ An 8 phase intersection has how many rings? Answer: 2
◉ What is a barrier? Answer: An interlock in a multi-ring controller,
or compatibility line, phases on one side of the barrier will never
operate with phases on the other side of the barrier
◉ What is a concurrent phase? Answer: Can be on with another
phase in its concurrent group i.e 1&5 or 2&6
