Is it necessary to gather all drawings prior to performing any electrical installations, according to federal law?

Gathering all drawings prior to performing electrical installations is not a requirement according to federal law. Federal regulations do not mandate that contractors must have every drawing in hand before starting installation work. The necessity for such documentation can depend on various factors, including the specific project requirements, local regulations, and the complexity of the installation. In many scenarios, contractors may start working with preliminary designs or schematic drawings, which can later be supplemented as the project progresses and more detailed plans are finalized.

For contractors operating in any jurisdiction, it's crucial to be aware of state and local regulations that may impose specific requirements regarding documentation. Additionally, for significant or complex installations, it is typically advisable to have access to complete drawings to minimize errors and ensure compliance with safety standards and codes, though this is more a matter of best practice rather than a legal obligation at the federal level.
