#1
What is the purpose of using a kick in conduit bending?
To create a bend
ExplanationKicks in conduit bending are used to create bends, typically at a 90-degree angle, by offsetting the conduit from its original path.
#2
What does the term 'stub-up' refer to in conduit bending?
A short length of conduit projecting above a surface
ExplanationIn conduit bending, 'stub-up' refers to a short length of conduit that extends above a surface, commonly used for making connections.
#3
What is the purpose of using a hand bender's arrow when making a bend?
To indicate the bend direction
ExplanationThe arrow on a hand bender is used to indicate the direction of the bend, ensuring accurate and precise bending in the desired direction.
#4
In conduit bending, what is the term for the curved part of the conduit between two bends?
Sweep
ExplanationThe curved part of the conduit between two bends in conduit installation is referred to as the 'sweep,' adding flexibility to the overall conduit run.
#5
What is the term for the angle formed between the straight portions of a conduit run in a back-to-back bend?
Included angle
ExplanationThe angle formed between the straight portions of a conduit run in a back-to-back bend is referred to as the 'included angle,' determining the overall direction of the conduit run.
#6
Which conduit bending tool is commonly used for making offset bends?
Hand bender
ExplanationHand benders are frequently used for making offset bends in conduit installations, providing versatility and control.
#7
What is the purpose of using a level during conduit bending?
To check for bends' alignment with the horizon
ExplanationA level is used during conduit bending to ensure that the bends align with the horizon, maintaining accuracy and proper installation.
#8
What is the purpose of a back-to-back bend in conduit installation?
To avoid obstacles and obstructions
ExplanationBack-to-back bends in conduit installation are used to navigate around obstacles or obstructions, providing a smooth and continuous conduit run.
#9
Which type of conduit material is commonly used for outdoor installations due to its resistance to corrosion?
Aluminum
ExplanationAluminum is frequently chosen for outdoor conduit installations due to its resistance to corrosion, ensuring durability in various weather conditions.
#10
What is the standard angle for a 3-point saddle bend in conduit installation?
45 degrees
ExplanationThe standard angle for a 3-point saddle bend in conduit installation is 45 degrees, providing proper support and clearance over obstacles.
#11
What is the advantage of using an electric conduit bender over a manual hand bender?
Faster bending speed
ExplanationElectric conduit benders offer faster bending speeds compared to manual hand benders, improving efficiency in conduit installation.
#12
In conduit bending, what does the term 'gain' refer to?
The distance between bends
ExplanationIn conduit bending, 'gain' refers to the distance between bends, a crucial measurement for accurate conduit installation.
#13
What is the purpose of using a multiplier when calculating conduit bend measurements?
To adjust for the conduit's springback
ExplanationA multiplier is used in conduit bending to adjust measurements for the conduit's springback, ensuring the final bent shape matches the intended specifications.
#14
What type of conduit bending method is typically used for large-radius bends in heavy-gauge conduits?
Ram bending
ExplanationRam bending is commonly employed for large-radius bends in heavy-gauge conduits, providing efficient and controlled bending.
#15
What is the recommended method for bending rigid metal conduit (RMC) to avoid kinking or flattening?
Segmented bending
ExplanationSegmented bending is the recommended method for bending rigid metal conduit (RMC) to prevent kinking or flattening, ensuring a smooth and accurate bend.
