Yes. Actually they should be run in the same conduit. You don't ever want to run parallel separately.

What size feeder wire for three phase 320 amp meter serving two 200 amp panels?
2/0 if copper is used; 4/0 if aluminum is used. The neutral and ground are usually smaller. 2/0 is only rated for 185 amps. 3/0 copper is rated for 210 amps, 250 MCM is rated at 215 amps if aluminum is used.
Array is value type or reference type in CSharp?
Array is a class name, hence ought to be a value type.
What is mcm wire?
MCM is another measure of wire gauge. It is somewhat confusing but it starts at around 40 gauge being the smallest wire up to the largest gauge of 1. from there you have oughts which is from 1 to 4 (1 ought, 2 ought etc) and then you have MCM which is circular mils. MCM can range from something as small as 250 mcm up to 2000 mcm.Another AnswerThe abbreviation, 'MCM', stands for 'thousand circular mils'. A 'circular mil' is a North-American method of measuring the cross-sectional area of a circular-section conductor (Europeans use square millimetres for conductors of anyshape).A 'circular mil' is obtained by squaring the diameter of a circular-section conductor, expressed in mils. A 'mil' is one-thousandth of an inch. As the constant, 'pi', isn't taken into account, it should be obvious that a circular mil is, therefore, a figure representing a cross-sectional area, rather than a true measure of that area.If necessary, in order to obtain a true cross-sectional area, circular mils can be converted into square mils.
When a 10 ohm resistor is connected in parallel to a 15 ohm resistor what percentage of the total current will flow through the 10 ohm resistor?
There will be 20 amps flowing through the 5 ohm resistor. We could do some math and all to figure voltage drops and some other things, but let's cut to the chase and see what's happening. Based on what we know about series circuits and about parallel circuits, we can shred this in nothing flat. So let's. First, we're told 30 amps flows in the circuit. That's the total current, and it will be the current through the first 10 ohm resistor. It has to be. The the 30 amps "splits" to flow through the parallel network of the 10 ohm and 5 ohm resistors. That's 30 amps that has to "split" and some will go through the 10 ohm resistor and some will go through the 5 ohm resistor. With me? Sure. Now for the "trick" here. Since the 5 ohm resistor has only half the resistance of the 10 ohm resistor, twice as much current will flow through it as the 10 ohm resistor. Make sense? Yup. Let's finish this. Since there is twice as much current flowing in the 5 ohm resistor 'cause it's got half the resistance of the 10 ohm resistor, if we have "x" amount of current flowing in the 10 ohm resistor, then we'll have "2x" amps of current flowing in the 5 ohm resistor. That's "3x" amps total, and the "3x" amps equals 30 amps. See through it now? There will be 10 amps flowing through the 10 ohm resistor, and 20 amps flowing through the 5 ohm resistor. Piece of cake.
What is meant by E learning?
Creating and commercialism online courses may be a moneymaking business. However, success typically depends on the LMS software package (Learning Management System) that you use. A top-quality LMS resolution can change you to style fascinating and varied courses that will interact with your students and keep them returning for many.

Seek options like multiple payment gateways, sales pages, occurrence payments and subscription choices, coupons, and more.
What size service conductors do you need for a single phase 600 amp commercial panel?
The size of wire for service entrance conductors for a 400 amp 3 phase service could be 500 MCM copper. This is very large size wire and difficult to bend and shape, to connect to terminals in the main disconnect and distribution panel. This problem is solved by using parallel conductors or on higher ampacities triple conductors. Using parallel conductors the wire size would be three ought (3/0) copper.
How many amps can 4 ought aluminum wire carry?
Aluminum 4/0 wire car carry 180 amps at at 75 degrees Fahrenheit or 205 amps at 90 degrees. .
What size rigid conduit for 200 Amp service entrance using 3 ought wire?
A 3/0 wire with an insulation factor of 90 degrees C is rated at 210 amps. The electrical code book states that 3 - 3/0 wires can be pulled into 41 mm conduit (1-1/2"). Most mast kits utilize 53 mm (2") schedule 40 conduit.
What size Aluminum wire is used for ground in breaker box?
For a 100 Amp breaker panel it would be 2 AWG. For 150 Amps it would require 2/0 (2 ought) aluminum wire.
What is the past tense of ought?
The past tense of ought is ought.
What wire size for 125 amp service?
The short answer, if using copper, is 0 AWG, commonly referred to as 1/0 or "one ought". Type of wire depends on location & temperature, but in my common scenario I am using 1/0 THHN inside a 2" schedule 40 PVC conduit (3 - 1/0 wires plus a 4 ga bare ground) to run indoors, a distance of about 25 feet from my main panel to a sub for upstairs. I could go into more detail regarding outdoor, direct burial, grounding, aluminum wire, etc but would need more details.
How do you say ought in past tense?
Ought is already acceptable in past tense. 'Ought to be' is present tense, while 'Ought to have been' or 'Ought to have' is past tense.
How many amps can a zero gauge wire handle?
You are probably thinking about 1/0 wire (1 ought wire). In copper it is rated at 175 amps and in aluminum 125 amps.
What is a sentence with the word ought in it?
A sentence with the word ought in it is: "I ought to be a superstar someday!"
Which is the largest buckshot triple ought double ought or single ought?
Triple ...
Ought - antonym?
The antonym of "ought" in the sense of should is "shouldn't" or "ought not:""Jack ought to have joined in the fun.""No, he shouldn't have joined in if it wasn't fun for him."
When you use ought?
"You ought to be doing your homework."
