Which of the following details is typically NOT required in the installation documentation?

The detail that is typically not required in installation documentation is labor costs. Installation documentation primarily focuses on technical specifications, compliance with standards, and safety measures necessary for the proper setup and operation of electrical systems.

Manufacturer's information is crucial as it provides data on warranty, support, and compliance with regulatory standards. Similarly, details regarding battery technology or type are essential for ensuring compatibility with the broader system and for understanding performance characteristics, such as discharge rates and charging protocols.

Short circuit current ratings are important in the documentation as they help assess safety measures and protective device ratings, which are critical to preventing equipment damage and ensuring safety in electrical systems.

Labor costs, while important for project budgeting and financial planning, do not influence the technical compliance or performance of the electrical installation itself. Therefore, they are usually not documented in the technical installation documentation required by regulatory bodies or industry standards.
