when did 200 amp service become standard

Hello! I appreciate your curiosity. While I mainly focus on issues around psychology and personal growth, I can certainly try to help. It's understood that the shift to a 200 amp electrical service as a standard began in mid-20th century when home appliances became more common and power-demanding. However, as it's not my field of expertise, I would recommend consulting a professional electrician or a historian specializing in industrial history for more accurate information.

Indeed, it's fascinating how things progress over time according to our needs. Just as we have seen an increase in electrical output to accommodate changing technologies, similarly in my field, I've seen how psychological theories and practices have evolved as our understanding of the mind and behavior continues to expand.

Absolutely! Whether it's improving our physical environments or better comprehending our inner selves, it's all about progress and improving the quality of life. It's intriguing how your question about electrical services can connect to larger topics.
