what are the 4 wires on a dryer - IOT Wiring Diagram

The 4 wires on a dryer are the power supply cords, grounding wires, and high-voltage wires. These four wires need to be correctly connected for the dryer to work properly and safely. In many cases, electricity-related accidents can be linked to mishandled wiring, so it's critical to understand how to install and use your dryer correctly.

The power supply cord is the first of the four wires on a dryer. This cord is usually colour-coded to reflect how it's to be wired up, with three phase colours – black, red, and white. This cord should be connected to a 240-volt circuit with its own dedicated circuit breaker and should always be connected with the correct wire gauge and amperage rating. The next wire is the grounding wire, which needs to be connected to a grounding point to ensure the dryer remains securely grounded and is safe from electrical shock or fire hazards.

The third wire is the high voltage wire. This is the wire that will carry the power to the dryer’s heating element. This is usually a thick, red or orange-coloured wire and it's important to make sure it is connected correctly to the right terminals on the dryer. Finally, the fourth wire is the neutral wire. This is typically a white wire and is used to balance the electrical load on the system. All four of these wires must be correctly wired for the dryer to work safely and efficiently.

Installing and using the four wires correctly on your dryer is essential for the safety of your home and those who live there. If you're not confident in installing these yourself, it's best to call in a professional electrician who will be able to safely wire your dryer. Taking the time to check and make sure your dryer is properly connected and wired up will save you money and ensure the safety of you and your family in the long term.
