Electrical work is gruelling enough without having to create perfect sculptures. Ironically, bending conduit to jump over architectural obstacles is one of the most challenging aspects of electrical work. A botched bend can cost time and money, especially when using aluminium conduit. A few inches off in either direction could be disastrous and prompt a timely trip to the hardware store. Take your time, use the appropriate conduit bender, and know your angles.

Measure the height of the object you intend to "jump" with the conduit.

Choose how sharp or soft an angle you want the conduit to take. A common angle for offset bends is 30 degrees.

On the conduit bender, one side has a list of angle degrees. Find the 30-degree indicator.

Turn the conduit bender over to find the depth multiplier that corresponds to 30 degrees. For 30 degrees, the depth multiplier is 2.

Multiply the height of the object to be jumped by the depth multiplier. If the object is 10 inches high, the total distance between 30 degree bends will be 20 inches.

Mark off 20 inches on your conduit with a sharpie and place one marked end in the bender.

Bend away from the floor until the bottom of the conduit reaches the 30-degree marker on the bender.

Place the other end of the conduit in the bender, lining up the angle of the bend. Bend towards the floor until the bottom of the conduit reaches the 30-degree marker.


Always use a conduit bender.
