What is the maximum allowable conductor fill of any trade size conduit used as a raceway?
It depends on the wiring, the current load in the wiring , and the distance. The NEC Code book has the charts for this.And the size of the conduit.

What size conduit do I need for 6 wire. Being hooked up to a spa?
The minimum size you can use is 3/4 conduit. The code allows for a maximum of 4 each # 6 gauge wires in a 3/4 inch pipe. You'll likely be running 3 ea # 6s, two hots and the neutral and a #10 ground wire.
When grounding a metal box what must be done?
The grounding system of a distribution must be from zero ohms to a maximum of two ohms. This is usually obtained by bonding all metallic parts back to the distribution centre with a wire capable of handling the circuits fault current if the circuit should ground out. The ground wire in cable sets is used for this purpose.
What is maximum power rating?
Maximum power rating describes the maximum power at which a device can operate without reaching an excessive temperature. For example, in the case of a resistor, if its maximum power rating is exceeded, then it may burn out.
What is the maximum degrees bending for conduit?
The maximum degrees of bending allowed for conduit typically ranges from 90 to 360 degrees, depending on the type and size of the conduit. It is important to consult local building codes and manufacturer specifications to determine the specific maximum degrees of bending allowed for a particular conduit. Incorrect bending can cause damage to the conduit and affect the performance of the electrical system.
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.
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.

What is the maximum distance service entrance conductors can be installed in conduit inside a residence before entering the service panel?
Service entrance conductors should not be installed in conduit more than 10 feet inside a residential building before entering the service panel. This helps ensure efficient delivery of electricity and compliance with safety codes. It is important to follow local electrical codes and regulations for specific guidelines.
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 the maximum weight a flexible cord can support?
The maximum weight a flexible cord can support depends on its material, thickness, and construction. It is important to consult the manufacturer's specifications or guidelines for the specific cord being used to determine its maximum weight capacity. Overloading a cord beyond its weight limit can lead to failure and potential safety hazards.
What size conduit for 400amps?
The sizing of conduit systems that wire has to be pulled into is dependant on the physical size of the conductor being drawn into the conduit. The second governing factor is the conductor count of the specific conductor that is needed. A 500 MCM copper conductor with an insulation factor of 90 degrees C is rated at 430 amps. This is where the conductor count is need by the service, as to whether the service is single or three phase. In this specific case, the electrical code will allow both single and three phase installations to use the same size conduit. A maximum total of four 500 MCM conductors can be drawn into a 78 mm diameter conduit.

What is the element having maximum non metallic character?
Fluorine has the highest non-metallic character among all elements. This is due to its high electronegativity and small atomic size, which result in strong attraction for electrons and a tendency to gain electrons to achieve a stable electron configuration.
Can you install more than 8 conductors of 480 volt in a 2conduit?
That depends on the size of the conductor and the type, which is defined by its insulation. With many common large feeder conductors such as THHW, the largest conductor which you can run 8 of is # 2 gauge. Whereas common small branch circuit conductors such as # 12 THHN, you can run 138 ea. through a 2 " conduit. For the complete list, look at the chart titled "Maximum number of conductors in electrical metallic tubing" (EMT) in the National Electrical Code.
