Answer:
stainless steel
Explanation:
Conductivity refers to the degree to which a specified material conducts electricity. It is the ratio of the current density in the material and the electric field.
The thermal conductivity of a material measures its ability to conduct heat.
In materials of low thermal conductivity, heat transfer occurs at a lower rate as compared to materials of high thermal conductivity.
Thermal expansion of the material refers to its tendency to change its shape, area, and volume as a result of change in temperature.
The electrical resistance of a material refers to the measure of its opposition to the flow of electric current.
<u>Stainless steel</u> has a lower coefficient of thermal conductivity along with a higher coefficient of thermal expansion and higher electrical resistance.
The specific grounding and bonding requirements for an information technology room are located in Article 645.
<h3>What does NEC stand for?</h3>
The National Electrical Code (NEC) is a collection of requirements for the secure installation of electrical wiring in the US that are routinely updated.
Bonding is the joining of conductors that do not convey current, such as enclosures and buildings. Bonded systems are attached to the earth by grounding. To protect persons and property from electric risks, both are required.
Article 645 compliance is optional. The two main pardons provided by Article 645 are. First, underneath a raised floor, non-plenum-rated cables are acceptable. Second, cables, boxes, and similar items for the mentioned IT equipment are exempt from the need for security. sted IT equipment cables, boxes, and the like are not required to be secured in place.
