What is the offset when using a conduit bender?
The offset is the preset distance that is marked on the shoe of the bender. This preset mark allows for shrink back when bending. It allows you to make a perfect bend if a conduit run comes to a wall and has to go up the wall. It takes into account the outside diameter of the conduit and adds it to the shrink back of the bend to make the conduit fit exactly up against the 90 degree angle of the wall.See Sources and Related links below.
What are the 4 types of electrical conduit bend?
The 'Stub-up', or 90º bend, Back to Back Bends, Three Bend Saddles, and offset bends.
How many degree bend permitted in conduit run?
Answer for USA, Canada and countries running a 60 Hz supply service.A total of 360 degrees between openings, regardless of distance, is the NEC's limitation. From experience I know that any time you go beyond 270 degrees you are going to have a difficult pull regardless of what other steps you take.360 degrees = 4 - 90 degree bends270 degrees = 3 - 90 degree bendsAs always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
What is offset current?
On a differential amplifier while there is some voltage offset there is also current offset which is dependent on the value of the F/B resistance the bigger value the more offset.
How can an OP-AMP be nulled?
op-amp can be nulled using offset voltage about +/- 1.5 mv to offset pins
What multiplier would be used for EMT conduit to make a 45 degree offset bead?
The multiplier for a 45 degree bend is 1.4142 (rounded off to 1.4) times the height of the offset. All offset multipliers are the cosecant of the angle. (inverse of the sine of the angle). However, 45 degree offsets are very difficult to pull wire through and should be avoided. Always bend your EMT to the shallowest angle you can for the distance you have to do it in.

A 10-inch beam is in the path of a conduit run from a junction box which is located 38 inches from the beam The beam is to be bypassed by a 30-degree offset with the second offset bend occurring at t?
It is easier that you bend the conduit around the beam or pierce the conduit throough the beam, depending on how big the conduit is.
When bending a 12 inch offset using a 30 degree bend what would the distance between the two bends?
Use these numbers when bending offsets: 10 degree bends, multiply the depth of the offset by 6 this will give you the distance between bends. For 20 degree multiply by 2.6, for 30 degree multiply by 2, for 45 degree multiply by 1.4, for 60 degree multiply by 1.2. I use 30 degree bends for all of my offsets, just because its easier to do the math. So your answer would be 24 inches between bends. I have come to the conclusion anybody can bend conduit, its the measuring and marking that requires skill.

How many degrees of bend is allowed in a conduit run between j-boxs?
The electrical code states that there will be no more that four quarter bends between junction boxes. Keep in mind when conduit bending that an offset of two 45 degree bends is classed as a 90 degree bend. Offsets between two junction boxes uses up two of the four 90 degree bends allowed. If in a conduit run, the limit of 90 degree bends is utilized, always pull in stranded wire to make the pull go easier.
What is the total shrinkage of a set of 30 degree offset bends with a depth of 7 in and a set of 22 12 degree opffset bends with a 4 in depth?
To find the total shrinkage, you would add the shrinkages of the two sets of bends together. For the set of 30 degree offset bends with a depth of 7 inches, you would calculate the shrinkage using a bender multiplier table based on the bend angle and a depth of 7 inches. Similarly, you would do the same for the set of 22 1/2 degree offset bends with a depth of 4 inches, and then add them together to get the total shrinkage.
How many degrees of bend is allowed in a conduit between boxes?
It is generally recommended not to exceed 360 degrees of total bends in a conduit run between boxes. Any more bends may make it difficult to pull wires through the conduit and can affect the efficiency of the electrical system.
