NECA Manual of Labor Units (MLU), PDF Download (4090-19D)

An estimate is only as good as the information it is based on, and the NECA Manual of Labor Units (MLU) has been the estimating resource of choice for electrical contractors since 1923. The MLU provides an experience-based reference for estimating the electrical construction labor required to install typical electrical and communications systems. 

Updates to this edition provide new units for LED fixtures, 35KV cable and more, as well as a new keyword index to provide a better user experience when locating labor units.
