Who has developed the drawing standards for symbols used in electrical prints?

The correct answer is ANSI, which stands for the American National Standards Institute. ANSI has established the drawing standards for symbols used in electrical prints, ensuring consistency and clarity in electrical schematics and designs. These standards help engineers, electricians, and technicians communicate effectively and avoid misunderstandings when interpreting electrical diagrams.

ANSI’s role in developing these standards promotes safety and efficiency in electrical work by providing a universally recognized set of symbols and terminology. This is essential for anyone involved in electrical installation, maintenance, and design, as it allows professionals to work from the same reference points, thus streamlining processes and enhancing the overall quality of electrical work.

While organizations like IEEE and ISO also contribute to standards in their respective fields, ANSI is specifically geared towards American standards for electrical and other engineering practices. The NEC (National Electrical Code) primarily focuses on safety and installation regulations rather than drawing standards, making ANSI the appropriate choice in this context.
