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 .
How is an electrical conduit installed?
Conduit Installation: 9 Steps Step 1: Mark Conduit Placement: Using a measuring tape, mark the locations where the conduit will be installed, including entry and exit points, bends, junction boxes, and supports. Step 2: Cut and Prepare Conduit: Measure the required length for each conduit section based on your markings. Use a conduit cutter or hacksaw to make clean, straight cuts on the conduit. Step 3: Install Conduit Fittings: Attach the appropriate conduit fittings, such as elbows, couplings, or connectors, to the conduit sections. Step 4: Mount Conduit Supports: Install conduit straps or clamps at regular intervals along the conduit route. Step 5: Assemble the Conduit System: Connect the conduit sections and fittings together, ensuring a snug fit. Apply PVC conduit cement or glue to the inside of the fittings before joining them to ensure a watertight seal. Step 6: Pull Wires: Attach a fish tape or draw wire to the starting point of the conduit system. Carefully feed the fish tape through the conduit, pulling it along the desired path. Use lubrication, if necessary, to ease the wire pulling process. Step 7: Install Conduit Accessories: Install conduit bodies, junction boxes, or other accessories as needed for wire splices, changes in direction, or access points. Step 8: Verify and Secure Connections: Double-check all connections, ensuring they are properly aligned, secure, and free from any gaps or looseness. Step 9: Conduct Final Inspection: Inspect the entire conduit system to ensure it is properly aligned, securely mounted, and meets safety standards. Check for any visible defects, such as misalignments or damaged conduit. That's it.
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 is advantage and disadvantage of impedance coupling?
The term impedance coupling can be used in two ways. 1) Example, coupling a signal from the output of one stage of an amplifier, to the input of the next stage. For low power as under about 0.1 watt, RC coupling is cheap and adequate as little power is dissipated in the collector resistor of a bipolar amplifier. However at higher power levels impedance coupling is more efficient, but also more expensive. An inductor simply replaces the resistor used for RC coupling. Unlike a resistor the inductors impedance is frequency dependent. This varies the level of coupling voltage available over the amps bandwidth, and needs to be accounted for at the design stage. An advantage is that by the addition of a parallel capacitor, an LC circuit can be formed to produce the basis for a band pass amplifier. Further by providing a tapped inductor; coupling, tuning and impedance matching functions can be obtained. Transformer coupling is a form of impedance coupling and can provide galvanic isolation as well as matching. 2) Unbalanced circuits, that is those having a 'high' or 'signal' lines and a common ground,chassis or earth; have the disadvantage that undesired signal coupling can occur when the higher current signals produce small voltage drops along the common ground. To minimize these undesired voltage variations grounds on PCBs are given wide low resistance tracks. Also by not mixing analog and digital signal grounds, the adverse effects of coupling are reduced. Furthermore, at higher frequencies a narrow length of track also has inductance, and capacitance to nearby conductors. There components provide the possibility of additional undesired impedence coupling. Balanced circuits which do not have one line of any signal grounded overcome the disadvantages of the simpler unbalanced circuits.

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.
The largest conduit trade size in which a short nipple of 2.5 inch length is available is?
3inches
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.
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
