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 bends
270 degrees = 3 - 90 degree bends

As 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.

According to the National Electrical Code (NEC), in a straight run of conduit, you can have a maximum of 360 degrees of bends. Since a 90-degree bend counts as 90 degrees, you can have up to four 90-degree bends in a 70-foot run of conduit. However, if the conduit is longer or includes additional fittings, it's essential to consider the total degree of bends and plan accordingly. Always consult local codes and regulations, as they may have specific requirements.
The maximum number of 14 AWG wires allowed in a half-inch conduit depends on the type of conduit and local electrical codes. According to the National Electrical Code (NEC), for a standard half-inch EMT conduit, you can typically fit up to 9 conductors. However, it's important to check the specific NEC tables and local regulations, as factors like insulation type and conduit fill rules can affect the final count. Always consult a qualified electrician for precise calculations.

There has to be a pull box between every four quarter bends in a conduit run.
How many inches do you deduct for a 90 degree bend on 3/4" conduit:
4
6
6 nches
For a 90-degree bend on 1.5-inch conduit, you typically deduct 10 inches from the total length of the conduit. This deduction accounts for the bend's radius and allows for proper installation. Always refer to local codes and guidelines, as requirements may vary.
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.

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.
The "How Many Wires in PVC Conduit" chart typically accommodates up to 9 wires in a PVC conduit.
