∙ 14y agoNEC allows four quarter bends between junction boxes and conduit bodies for a total of 360 degrees. You can have more than four bends, but all of the degrees of the bends can not add up to more than 360 degrees.

∙ 12y agoIn general, it is recommended to limit the number of bends in conduit to 360 degrees (four 90-degree bends) for proper cable installation. Exceeding this limit can affect cable performance, make pulling cables difficult, and increase the risk of damage to the conductors.

∙ 14y agoThe electrical code states that there shall not be more than 4 90 degree bend between pull boxes. Keep in mind that an offset going into a box is equal to one 90 degree bend.

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.
The electrical code states that there shall be no more than four 90 degree bends in a conduit length between pull boxes. This equals 360 degrees. The first scenario 90 + 90 + 45 + 45 + 45 + 45 = 360 degrees so that conduit run is acceptable. The second scenario 90 + 90 + 30 + 30 + 30 + 30 +30 = 330 degrees so this combination is also acceptable.
Per national electrical code you are only allowed 360 degrees which is 4, 90 degree bends before having to use a pull box or termination.
It is recommended to limit the number of 90-degree bends to 360 degrees in one run from Box A to Box B to prevent excessive resistance and impact on cable performance. This means you can have up to four 90-degree bends in a single run.
An electrical pull box is a junction box used to facilitate the pulling of wires during installation. It provides a space to make wire connections, protect them from damage, and allow for future access. Pull boxes are typically installed where multiple conduits need to be connected or when a change in direction is required.
Code states no more that 4 - 90 degree bends in a conduit run between pull boxes.
There has to be a pull box between every four quarter bends in a conduit run.
Yes. You have to have a pull box every 4 90s or every 100ft. Which ever comes first.
All conduit shall not have more than 360 degrees for it's length between either a box, cabinet, or conduit body. Couplings count as a continuation of conduit.

Bends are made in PVC conduit using a tool known as a heat gun or a heat blanket. If you want to make make accurate and aesthetically pleasing bends without distorting the pipe, the PVC conduit must be heated thoroughly - inside and out. This is achieved using a "heater box," or a "heater blanket." Greenlee tools makes both, specifically for working with PVC conduit. Also available are plugs for plugging the ends of the PVC lengths to be bent, for keeping heat trapped inside the pipe and speeding up the heating process.
When exist a junction box EMT, conduit must be supported within 18 inches.

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.
