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.

What are electrical sleeves used for?
In the electrical industry there are many different types of sleeves used. There are insulation sleeves, linesman's high voltage sleeves and conduit sleeves to name a few. The insulation sleeve is used for the protection of electrical conductors. Linesman's sleeves are used for extensions to the protective rubber gauntlets that they wear when working on high tension wiring systems. Conduit sleeves are used when a broken conduit needs to be repaired in situ.
How do you pull wire in conduit?
There are both industrial and home owner cable pulling techniques. The former may involve heavy equipment and cable greasing and many people. Pulling cable on a small scale involves a snake and sometimes a pull cord. A snake is a coiled metal strip that you push through the conduit. When it comes out the other end or to a pull box you connect the wire and pull it back through the conduit. If more wire might be pulled later, also attach a pull cord so it will be left behind in the conduit for future use.

How many degrees of bend is allowed in a conduit run between j-boxs?
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.
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.
How many inches do you deduct on a 90 degree bend on half inch bend?
6 inches
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 wires are typically accommodated in a PVC conduit according to the "How Many Wires in PVC Conduit" chart?
The "How Many Wires in PVC Conduit" chart typically accommodates up to 9 wires in a PVC conduit.
How many No2 Awg THHN wires will fit in a 1 conduit?
Approximately 6-8 No. 2 AWG THHN wires will fit in a 1" conduit, depending on the manufacturer and bending restrictions. However, it is always recommended to consult the National Electrical Code (NEC) and local regulations for specific guidelines on conduit fill for your location.
Where is Conduit Street located?
Conduit Street is located in the Mayfair section of London, England. Along Conduit Street you will find many different shops, clubs, restaurants and stores.
How many markings should a rigid nonmetallic conduit have?
There will be at lease three and on some conduits additional information. There will be the manufacture's name, type of material the conduit is manufactured from and the diameter size of the conduit. For example Scepter PVC 100 mm (for American customers 4") conduit.
