An estimate is only as good as the information it's based on. Since 1923, the NECA Manual of Labor Units (MLU) has been the estimating resource of choice for electrical contractors, providing an experience-based reference for the labor required to install typical electrical and communications systems. The 2025-2027 edition is here, and every NECA member gets a copy.
