Electrical Unit Setup and Safety

The video tutorial guides students through setting up an electrical unit, focusing on running feed wires, connecting them to a switch box, and ensuring safety through proper grounding. It covers stripping wire ends, creating hooks for connections, and assembling the switch. The tutorial concludes with testing the setup using a safe voltage system and disassembling the unit.

What is the first step in setting up the electrical unit?

• Connecting the light bulb

• Running feed wires into the switch box

• Testing the system

• Securing the light switch

When running a wire from the switch box to the light box, what is important to remember?

• The wire should be stapled to the floor

• The wire should be as short as possible

• The wire should be coiled tightly

• The wire should be long enough for demonstration

What is the purpose of the ground wire in the electrical setup?

• To provide power to the light bulb

• To return electricity to the panel box

• To act as a safety measure

• To connect the switch to the light box

How should the ends of the wires be prepared for connection?

• By painting them with conductive paint

• By wrapping them in insulation tape

• By stripping them using wire strippers

• By cutting them to different lengths

What is the correct way to connect the black wire to the light switch?

• Connect it to the silver screw

• Connect it to the brass screw

• Connect it to the green screw

• Connect it to the plastic hook

Why is it important to bend the wires like an accordion before securing the switch?

• To make the switch easier to remove later

• To prevent the wires from touching each other

• To ensure the wires fit easily into the box

• To make the wires look neat

What should be done before disassembling the electrical unit?

• Cut the wires without unplugging

• Remove the light bulb while it is still on

• Turn off the switch and unplug from the transformer

• Leave the system plugged in

What is the purpose of using a special transformer in this setup?

• To stabilize the current flow

• To provide a backup power source

• To reduce the voltage to a safe level

• To increase the voltage for the light bulb

What should be done with the wire nuts after disassembling the unit?

• Use them to connect new wires

• Leave them on the wires

• Save them for future use

• Throw them away

What is the final step after disassembling the electrical unit?

• Leave the components scattered

• Plug the system back in

• Store the tools and components properly

• Test the system again
