What size conductor is required for a 104 ampere continuous load that is protected with a 150 ampere breaker?

Answers

To determine the appropriate conductor size for a 104 ampere continuous load that is protected with a 150 ampere breaker, you should refer to the National Electrical Code (NEC) Table 310.15(B)(16).

Based on this table, a conductor with a size of 2 AWG (American Wire Gauge) would be suitable for your requirements, as it has an ampacity of 130 amps, which safely accommodates the 104 ampere continuous load and is protected by the 150 ampere breaker.In order for current to flow within a closed electrical circuit, it is not necessary for one charged particle to travel from the component producing the current (the current source) to those consuming it (the loads). Instead, the charged particle simply needs to nudge its neighbor a finite amount, who will nudge its neighbor, and on and on until a particle is nudged into the consumer, thus powering it. Essentially what is occurring is a long chain of momentum transfer between mobile charge carriers; the Drude model of conduction describes this process more rigorously. This momentum transfer model makes metal an ideal choice for a conductor; metals, characteristically, possess a delocalized sea of electrons which gives the electrons enough mobility to collide and thus affect a momentum transfer.

Steel or iron pipe grounding electrode shall be protected from corrosion by ______ protection.
250.53(5)(a)

Answers

According to the National Electrical Code (NEC) 2017, section 250.53(5)(a), steel or iron pipe grounding electrodes shall be protected from corrosion by a suitable corrosion protection coating and/or cathodic protection.

This means that steel or iron pipes used as grounding electrodes must be coated with a protective layer to prevent corrosion, which can weaken the pipe and impair its ability to provide a reliable electrical connection to the earth. The protective coating can be made of various materials, such as epoxy, plastic, or asphalt, and must be suitable for the specific soil conditions where the pipe will be installed.

In addition to the protective coating, cathodic protection may also be used to prevent corrosion. Cathodic protection involves using a direct electrical current to protect a metal object from corrosion by making it the cathode of an electrochemical cell. This can be accomplished by connecting a sacrificial anode, such as a magnesium or aluminum rod, to the steel or iron pipe, which will attract the corrosive current away from the pipe and onto the anode.

By protecting steel or iron pipe grounding electrodes from corrosion, the NEC aims to ensure the longevity and reliability of the grounding system, which is essential for maintaining electrical safety and equipment performance.

Answers

A DC generator that supplies rotor current to larger alternators is called an "exciter." Exciters are used to provide the initial electromagnetic field required for the alternators to produce AC voltage.

The photosystem's reaction centre, chlorophyll I transmits its excited electrons to ferrodoxin, a  exciter tiny protein on the stromal side of the thylakoid membrane, via a series of carriers. Then, ferrodoxin's electrons are transferred to NADP+ by the enzyme NADP reductase, producing NADPH.

Two water molecules are the source of the four protons and four electrons. Through an electron transport chain, the excited chlorophyll electrons are moved from photosystem II's electron acceptors to photosystem I.

Photosystems, the functional elements of photosynthesis, are recognised by particular pigment association and organisation patterns.

Answers

After a finally block has finished executing, control proceeds to the first statement after the finally block.

The finally block is executed regardless of whether or not an exception is thrown, so this ensures that any necessary cleanup or resource release is performed. Once the finally block completes execution, control continues to the next statement in the program, which is the statement immediately after the finally block. This behavior is important to keep in mind when writing code that uses try-catch-finally blocks, as any logic that needs to be executed after the try-catch-finally block should be placed after the finally block.

Answers

The given statement "A transitional off-to-on contact will allow logic continuity for one scan and then open, even though the Triggering signal may stay on." is true because a transitional off-to-on contact will allow logic continuity for one scan and then open, even though the triggering signal may stay on.

In ladder logic programming, a transitional off-to-on (TO) contact is a logic element that is used to detect a change in state from off to on of a signal. When the TO contact detects this change in state, it allows logic continuity for one scan cycle and then opens, even if the triggering signal remains on. This means that the TO contact can be used to generate a single pulse or to trigger an event based on a change in state.

For example, if a sensor detects a part on a conveyor belt and sends a signal to a PLC, a TO contact can be used to generate a single pulse to start a timer that controls the operation of a motor to move the conveyor belt. Even if the sensor continues to detect the part on the conveyor belt, the TO contact will only generate a single pulse and not continuously trigger the timer.

Note that no drug will precipitate from the solution upon cooling it to 40°C.

What is the explanation for the above response?

Amount of drug in saturated solution at 80°C = 1000 g

Solubility of drug at 80°C = 2.5 g B 100-1 g-1 water

Therefore, the amount of water present in the solution at 80°C = 1000 g / (2.5 g B 100-1 g-1 water) = 40000 g

Amount of drug in saturated solution at 40°C = 1000 g

Solubility of drug at 40°C = 0.36 g B 100-1 g-1 water

Therefore, the amount of water present in the solution at 40°C = 1000 g / (0.36 g B 100-1 g-1 water) = 2777.78 g

The amount of drug that will precipitate = amount of drug in initial solution - amount of drug in solution at 40°C

= 1000 g - (0.36 g B 100-1 g-1 water * 2777.78 g) = 1000 g - 1000 g = 0 g

The insulation on the conductors within type NM cable shall be rated at ______.
334.112

Answers

According to section 334.112 of the National Electrical Code (NEC), the insulation on the conductors within Type NM (non-metallic sheathed) cable shall be rated at a minimum of 90 degrees Celsius.

Type NM (Non-Metallic) cable, also known as Romex® cable, is a type of electrical cable used for indoor residential wiring applications. It typically consists of two or more insulated conductors, a bare or insulated ground wire, and a non-metallic outer sheath. The conductors are usually made of copper, and the outer sheath is typically made of PVC or similar material. Type NM cable is commonly used for branch circuit wiring in residential applications, such as powering lighting and receptacle circuits. It is easy to work with and install, and is designed to be used in dry locations only. In damp or wet locations, the use of moisture-resistant cables is required.
