I have often heard that aluminum wire is unsafe and copper is a better choice. Now IÃ¢â‚¬â„¢m in the process of finishing a new power pole install and found my local utility company (PG&E) requires aluminum wire from the service head to the meter. What is the story with aluminum vs copper wire? If copper is a superior wire why would they require aluminum?
