Galvanized steel construction offers what customer benefits?
Correct Answer
C. Both a and b
Explanation
Galvanized steel construction offers both superior corrosion resistance and high light reflectivity. The process of galvanizing involves coating the steel with a layer of zinc, which acts as a protective barrier against corrosion. This makes galvanized steel highly resistant to rust and other forms of corrosion, prolonging its lifespan and durability. Additionally, the zinc coating on galvanized steel has high light reflectivity, making it ideal for applications where increased visibility or reflectivity is desired, such as in outdoor signage or highway guardrails. Therefore, both of these benefits are provided by galvanized steel construction.

In the ANSI solution, the cells can be installed and operate in altitude (more than 1000masl) if surge arresters are installed, but the Insulation level is de-rated including BIL and power frequency
Correct Answer
A. True
Explanation
The explanation for the given correct answer is that according to the ANSI solution, cells can be installed and operate in high altitudes (more than 1000masl) if surge arresters are installed. However, in such cases, the insulation level, including BIL (Basic Insulation Level) and power frequency, is de-rated. This means that the insulation level is reduced or downgraded in order to account for the higher altitude, which can affect the performance and reliability of the cells. Therefore, the statement "True" is correct.
27.
When the Switchgear and MCC frames are direct coupled, the ratings of the complete Line up are the ones of the upper rating of both equipment
Correct Answer
B. False
Explanation
When the Switchgear and MCC frames are direct coupled, the ratings of the complete Line up are not necessarily the ones of the upper rating of both equipment. The ratings of the complete lineup depend on various factors such as the individual ratings of the switchgear and MCC frames, their compatibility, and the specific requirements of the system. Therefore, it is not always true that the ratings of the complete lineup will be the ones of the upper rating of both equipment.
