How many 90 degree bends can you have in one run of conduit from box A to box B?
In 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.
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.
What is a electrical pull box?
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.
Which one of the following combinations of bend in a conduit run require the use of a pull box two 90-degree bends and four 45-degree bends two 90-degree bends and five 30-degree bends?
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.
When light moves from one medium to another it bends however there is one exception to this rule what is it?
When light moves from one medium to another, it bends due to the change in its speed caused by the change in medium. One exception to this rule is when light passes perpendicularly from one medium to another, in which case it does not change direction but only its speed.

What triangle has two 45 degree angles and one 90degree angles?
It is an isosceles right angle triangle.
How many bends does a standard paperclip have?
A standard paperclip typically has two bends – one near the middle to create the looped shape and one at each end to form the two legs of the clip.

How many bends can a sewer vent have?
No more then 904 1/8th bends and on the VT usually one return bend 180 degree fitting to prevent vandalism BUT local codes should be checked
