Basic Electrical Installation
This is the standard unit used to measure electric current.
What is an ampere?
This tool is used to drive screws into electrical boxes, outlets, and fixtures.
What is a screwdriver?
This is the formula represented by Ohm’s Law.
What is V = I × R?
Even this low household voltage can be fatal under certain conditions
What is 120 volts?
This federal agency sets safety standards for electrical work in the U.S.
What is OSHA?
This safety device is designed to break the circuit when too much current flows, protecting both people and equipment.
What is a circuit breaker?
This device is used to measure voltage, current, and resistance in a circuit.
What is a multimeter?
In Ohm’s Law, the letter V stands for this quantity.
What is voltage?
You should never touch electrical devices with these parts of your body if they’re wet.
What are your hands?
Electrical PPE stands for this
What is Personal Protective Equipment?
The color of the earth/ground wire in most electrical wiring systems.
green or green with yellow stripes?
This tool is used to grip, twist, bend, or cut wire during installations.
What are pliers?
If a circuit has a resistance of 5 ohms and a current of 2 amps, this is the voltage
What is 10 volts?
This reaction occurs when the body completes an electrical circuit.
What is an electric shock?
This insulating gear is worn on your hands to prevent shock.
What are rubber gloves?
This type of wiring method involves running cables through steel or PVC tubing for extra protection.
What is conduit wiring?
Installed in distribution boards, this device automatically disconnects the power in case of a fault or overload.
What is a Miniature Circuit Breaker (MCB)?
Ohm’s Law shows that when resistance increases and voltage stays the same, this happens to the current.
What is it decreases?
This safety device trips when current leakage is detected, especially in wet locations.
What is a GFCI?
All lockout/tagout procedures begin with this step.
All lockout/tagout procedures begin with this step.
Before starting any electrical installation, this tool is used to ensure that there is no voltage present.
What is a voltage tester or multimeter?
This device is used to safely connect multiple circuits to a single power source and usually contains fuses or breakers.
What is a distribution board (or consumer unit)?
A light bulb rated at 60 watts operates on 120 volts. According to Ohm’s Law, the current flowing through it is this.
What is 0.5 amps?
This medical condition, caused by electric shock, results in rapid and irregular heartbeat.
What is ventricular fibrillation?
Only these qualified individuals should work on energized equipment.
