If you have a motor that must remain adaptable to several sizes of belts what is the maximum length of flexible metal conduit you can use before the conduit requires fastening?

Adding an extra length of shaft on the existing shaft to take extra pulleys will put an extra load on the bearings supporting the shaft. In the long term this would shorten the life of the bearings. The makers might be able to supply more information like the side-load specification for the bearings. If in doubt support the outer end of the shaft.

∙ 9y agoIn North America, rigid conduit, EMT or flexible conduit all have to be fastened or supported within 18 inches of where the conduit terminates into the connected device. Sometimes to adhere to this rule, added brackets have to be installed to hold the conduit. One suggestion might be to support the flex conduit by hanging it from a bungee cord.

Is it permitted to use flexible conduit over 6 feet in length as a grounding means?
No. The new electrical code change does not allow any flexible conduit to be used as a ground means. It is now required to have a green ground wire pulled into the conduit with the other conductors in the flexible conduit. This grounded bonding conductor is not counted as wire fill when calculating the size of the flexible conduit to use
What is The lightest duty and most widely used non-flexible metal conduit available for enclosing and protecting cabling and wiring is?
The lightest duty and most widely used non-flexible metal conduit for enclosing and protecting cabling and wiring is Electrical Metallic Tubing (EMT). It is made of smooth, galvanized steel and commonly used in commercial and industrial applications due to its ease of installation and affordability.
Which conduit is best - PVC or MS conduit?
For underground conduit runs, PVC is by far the better of the two conduit systems.
One problem when using rigid metal conduit in a residence is that installation of the conduit may?
Require professional expertise and tools due to the difficulty in bending the conduit to fit. This can increase installation costs and complexity. Additionally, the rigid nature of the metal conduit makes it less versatile for installation in tight or complex spaces.
What must be attached to the top end of a conduit riser where conduit is used in a service?
A service head or LB fitting must be attached to the top end of a conduit riser where conduit is used in a service. This provides a termination point for the conduit and allows for easy access to the conductors inside the conduit.
When running flexible conduit it is required to strap the inches from a box coupling or connector and requires a strap every feet thereafte?

What is a radiator hose?
It is a flexible conduit for the coolant to flow between the engine and the radiator.
Where could one purchase a flexible conduit for DIY purposes?
Do-It-Yourself meccas Lowes and Home Depot have flexible conduits for sale online and in their physical stores. Grainger also has flexible conduits on its website.
What is the difference between armored cable and flexible metallic conduit?
Armored electrical cable contains insulated electrical service wires protected by a flexible steel covering. Metallic Conduit is a tube or pipe though which we lay electrical cable.(Most commonly lighting cables).
What are electrical conduit fittings used for?
An electrical conduit is a tube used to protect and route electrical wiring in a building or nonbuilding structure. Electrical conduit may be made of metal, plastic, fiber, or fired clay. Most conduit is rigid, but flexible conduit is used for some purposes.
How far apart should straps be place on flexible conduit?
you need to strap within 12" of box and not to exceed 4.5" there after
Can you zip tie MI cable to conduit legally?
No, the electrical code requires that the mineral insulated cable be strapped at proper intervals and not be piggy backed on to other conduit structures.
Can a three phase circuit be installed in the same conduit or in different conduits?
The conductors of any three phase circuit must be run in the same conduit. If the circuit requires a neutral, it must also run with the conductors in the same conduit. (If they were to be run in more than one conduit or raceway, the circuit would not operate properly.)
To rewire a 2 bedroom property that was built in 1956 Can we use the old conduit or Do we need to replace it Currently earth is attached to the conduit itself Any special cables we can use?
If the existing conduit has not been intentionally or accidentally interrupted it is still an adequate ground. If you are in doubt about this or if a test proves that it is not grounded, new conductors including a new ground wire can be pulled inside the conduit. If the existing conduit is flexible conduit and it has "jake" type twist connectors, rewiring with a ground is advisable as those type of connectors do not maintain a good ground connection.
