NCCER Level 1 Module 7 Hand Bending Questions and Answers | Latest Version | 2024/2025 | Correct & Verified What is the purpose of hand bending in electrical installations? Hand bending is used to shape conduit to fit around obstacles and create the necessary layout for electrical wiring. What is the first step in bending conduit by hand? The first step is to measure and mark the conduit where the bend will be made. Why is it important to avoid overbending a conduit during hand bending? Overbending can weaken the conduit, causing it to crack or break, leading to unsafe conditions. What is the role of a conduit bender in the hand bending process? A conduit bender is used to shape the conduit at the desired angle and bend radius accurately. 2 What is the typical maximum angle for a standard bend in electrical conduit? A standard bend is typically made at a 90-degree angle. How do you ensure a smooth bend when using a hand bender? You should apply consistent pressure and maintain the conduit in alignment with the bender’s markings during the bending process. Why is it essential to follow the manufacturer's instructions when using a hand bender? Following the manufacturer's instructions ensures that the bender is used correctly, preventing damage to both the tool and the conduit. What can happen if you make a bend too tight for the conduit type? A tight bend can cause the conduit to collapse or deform, making it difficult to pull wires through and creating a safety hazard. What is the purpose of the "take-up" measurement when bending conduit? The "take-up" measurement accounts for the amount of conduit that will be lost during the bending process, helping to ensure the proper length of the bend. 3 Why is it important to avoid kinks when hand bending conduit? Kinks can restrict the flow of electrical wires, damage the conduit, and compromise the overall safety of the installation. What is a "3-point" bend and how is it used? A "3-point" bend involves making a 90-degree bend with a slight offset, often used when adjusting conduit around obstacles. How does the radius of a bend affect the conduit installation? The radius determines the smoothness and size of the bend; a smaller radius can cause damage, while a larger radius ensures safety and efficiency. What is the advantage of using a bender with a degree scale? A bender with a degree scale allows for precise and accurate bends, improving the overall quality and consistency of the installation. When should you use a "stub-up" bend in electrical installations? A stub-up bend is used when conduit needs to rise from a surface, typically to connect to a box or a panel. 4 How do you calculate the amount of conduit to be bent for a 90-degree angle? You can use the bend allowance calculation, taking into account the size and type of conduit, and applying the proper multiplier based on the degree of the bend.
