Answer: Tech B says manufacturers design circuits to operate in specific ways then create schematics or wiring diagrams to assist in the repair and maintenance of the designed circuits.
Answer:
TECH A is correct
Explanation:
Tech A saying that all lighting system wiring diagrams use the same symbols and numbering system is absolutely correct , this is because all lighting system wiring diagrams follow a particular engineering standard and procedure to ensure that every engineer regardless of where located can be able to read and interpret the lighting system wiring diagram when presented to him/her hence the use of same symbols and numbering system is true.
Engineers create schematics or wiring diagrams to assist in the repair and maintenance of designed circuits and not the manufacturer.
