How many 90 degree bends can you have in one run of conduit from box A to box B?
NEC 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.
How many degrees of bend is allowed in a conduit between boxes?
The electrical code states that there will be no more that 4 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.In a conduit run between J boxes the number of bends can not exceed 360 degrees.The electrical code allows four 90 degree bends between pull boxes.
What is a electrical pull box?
A pull box is a junction box that is placed in long conduit runs to make the pulling in of the wires easier. The code only allows 4 one quarter bends between pull boxes. If the conduit run incorporates more that 4 bends then a pull box has to be inserted into the run. The code allows up to the "equivalent" of four quarter bends or 360 degrees total before pull box 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
