The round prong on a cable is typically used for grounding purposes. It helps to prevent electric shocks and protects sensitive electronic equipment from power surges by providing a path for excess electrical current to flow safely to the ground.

What are the different sizes for plugs on a US dryer?

US dryers commonly use a 3-prong or 4-prong plug. The 3-prong plug has two flat blades (hot) and a L-shaped prong (neutral), while the 4-prong plug has two flat blades (hot), a round prong (neutral), and a half-round prong (ground). It's important to match the plug with the corresponding outlet for safety and proper functionality.


What has a purpose similar to that of the round prong?

A plug with flat prongs can have a similar purpose to a round prong plug, as they both serve as a means to connect electrical devices to power sources. The flat prongs are commonly used in North America, while the round prongs are more typical in Europe and other regions. Both types of prongs aim to establish a secure electrical connection for safe and efficient power transmission.


Which wire in a 240V cable with black white and bare copper wires connects to which prong in a 3-prong 30-amp 120-240V dryer outlet?

Do not use this type of cable to feed a 120/240V dryer outlet. The outlet is ungrounded, and the third conductor is neutral not ground. Your ground wire must be sheathed by code. You cannot use the bare neutral conductor as ground. Diagram Did Not Come Through. You Have a 3 Prong Connector. The Prong On The Bottom By Its Self Connect The Bare Wire. That Is What Was # 3 Connect The Others To The Two Prongs Next To Each Other. Hope This Makes Some Sense (1) (2) (3) Connect White To (1), Connect Black To (2) Bare (3) Good Luck

How can you tell if you have a 4 wire cable installed with a 3 prong outlet?

What you term as a four wire cable is known as a three wire cable in the electrical trade. The ground wire is not counted in the cable set as it is not a current carrying conductor. Turn the power off to the circuit in question. Remove the three prong outlet from the junction box. If you see a red, black, white and bare ground then you have a three wire cable feeding the receptacle. If this is what you see and the purpose of this question is to see if it can be changed to utilize a new four blade recepticle then the answer is yes.
