c-201 Electricals Systems 1 SACA Certification
Exam Questions And Answers
can you define and test a ground? - -a ground is a point in the circuit that is connected to
the earth. you can use a multimeter-If the resistance is too high, it may indicate that the
ground connection is not providing adequate protection
-electrical safety rules - -1.Always use a circuit tester or voltage detector to check that a
circuit is de-energized before working on it.
-electrical safety rule - -Never touch electrical wiring or equipment with wet hands or
while standing on a wet surface.
-electrical safety rule - -Do not operate electrical equipment that is damaged, frayed, or
otherwise in poor condition.
-electrical safety rule - -Use the correct fuse or circuit breaker for the circuit you are
working on.
-electrical safety rule - -Never remove or bypass the grounding prong on a plug.
-Electrical Safety - -Do not use extension cords or multiple outlet adapters that are not
rated for the equipment you are using.
-electrical safety - -Do not overload circuits by plugging in too many devices or using high-
powered equipment.
-electrical safety - -Do not use electrical equipment in wet or damp conditions unless it is
specifically designed for that purpose.
-electrical safety - -Use properly rated and properly installed surge protectors for
sensitive electronic equipment.
-electrical safety - -Always follow the manufacturer's instructions for using electrical
equipment.
-purpose of lockout tag out - -to prevent unexpected energization or startup of machinery
or equipment while it is being serviced or repaired.
-state the two types of electrical current - -AC and DC
-how to use a circuit tester - -To test a circuit, first locate the circuit breaker or fuse that
controls the circuit you want to test. Then, using the circuit tester, touch the red probe to
the live wire and the black probe to the neutral or ground wire.
, -what is a power source - -The power source is the source of electrical energy for the
circuit. It can be a battery, a generator, or a power outlet. The power source provides the
electrical current that flows through the circuit.
-what is a conductor - -The conductor is a material that allows electricity to flow through
it, such as a wire. The conductor carries the electrical current from the power source to the
load.
-what is a load - -The load is the device or appliance that is being powered by the circuit. It
can be a light bulb, a motor, or any other device that uses electricity. The load converts the
electrical energy from the circuit into some other form of energy, such as light or motion.
-what is a switch - -The switch is a device that is used to control the flow of electrical
current in the circuit. It can be used to turn the circuit on or off, allowing the load to be
powered or de-powered as needed.
-two types of power supplies and schematic symbol - -AC and DC
-be able to interperate an electrical schematic which includes symbols - -on youtube look
up engineering mindset- Single Phase Electricity Explained - wiring diagram energy meter
-resistor symbol - -
-Capacitor symbol - -
-inductor symbol - -
-ground symbol - -
-fuse symbol - -
-circuit breaker symbol - -
-lamp symbol - -
-switch symbol - -
-switch single pole double throw symbol - -
-normally open switch symbol - -
-normally closed switch symbol - -(bottom one)
-transformer symbol - -
