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

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.
When do you derate wires in conduit I know the code says more than 3 current carrying conductors but is there a length of conduit run when you should start to derate?
In general, you should start to derate when you have more than 3 current carrying conductors in a conduit. The length of the conduit run itself does not determine when you should derate. Stick to the guidelines provided in the electrical code for derating calculations to ensure safe and compliant installations.
Can you use PVC conduit underground?
Yes, PVC conduit can be used underground for electrical wiring. It is a common choice due to its durability, resistance to corrosion, and affordability. Make sure to choose the correct type and size of PVC conduit that is rated for burial to ensure safety and compliance with electrical codes.
What is a pipe In the volcano?
A vertical conduit through the Earth's crust; it connects the vent of a volcano to its magma chamber; a conduit through which volcanic materials pass. Commonly filled with volcanic breccia and fragments of older rock. Varies in width and length depending on location and type of volcano.
Minimum length of a grounding electrode?
A standard ground rod is 5/8 x 10'. The amount of rods needed is governed by the electrical code. The largest type of grounding system is a Ufer ground. This is where the bare grounding conductor is embedded in the footings of the building and the weight of the building presses the ground wire to the earths surface. These types of grounds are used mostly in construction and are requested by electrical engineers.

Are ground wires required in steel or aluminum flex conduits?
Yes, any flexible conduit that has live wires drawn into it must have a ground wire also installed with the "hot" conductors. The reasoning behind this rule is that the flex in the conduit is coiled and has a long length to it. The continuation of the grounding medium through the tightness of the conduit connectors to the flex was not considered a properly secured grounding system so to overcome this weakness in the grounding system, a ground wire now has to be installed.

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.
What is the multiplier for 45 degree offset in conduit bending?
Back set for all conduit sizes is not the same. The greater the diameter of the conduit the length of back set increases. Without the diameter size of the conduit, an answer can not be given.
Electrical conduit length is there a tool to measuring the conduit underground?
Well yes there is its called electricians conduit measuring tool we found it on u tube . go to superconduits and watch the video .
What is the maximum degree of bends allowed for 1 inch emt?
All conduit shall not have more than 360 degrees for it's length between either a box, cabinet, or conduit body. Couplings count as a continuation of conduit.
