Correct option is E
The correct answer is (e) (a) (c) and (d).
When selecting a control panel design, the following essential factors must be considered:
(a) Input voltage to the control panel: It's important to know the input voltage to ensure the components within the control panel are compatible and can safely handle the required electrical load.
(c) Input current to the control panel: The input current affects the sizing of the components such as wires, fuses, and circuit breakers. It helps in determining the appropriate protection and load-carrying capacity of the panel.
(d) Control panel size: The size of the control panel must be considered to ensure it accommodates all components, allows for proper ventilation, and meets the installation space constraints.
Information Booster:
Indicating lights (Option b) and weight (Option e) are secondary factors, though relevant, they are generally not as critical in determining the essential design of the control panel compared to electrical specifications like voltage, current, and size.
Additional Information:
The control panel design should also factor in safety standards, environmental conditions (e.g., temperature, humidity), and ease of maintenance.
