2022-2023 License and Installation Concerns Bulletin.

The Electricians' Licensing Board in conjunction with the State Electrical Inspectors, municipal electrical & building inspectors & other representatives of the electrical industry in the State of New Hampshire have put together this list of common licensing and installation concerns and problems encountered by the Board's office staff relative to the State's licensing law RSA 319-C and the administrative rules.

Section 110.3(B) requires equipment that is listed, labeled, or both shall be installed and used in accordance with any instructions included in the listing or labeling.

When specific installation requirements are provided by the manufacturer, they must be adhered to by the installer. All too often, the information provided on or with electrical equipment is disregarded by the installer. A common example found by inspectors is included below:

Installation and securing of expansion fittings in runs of Rigid Polyvinyl Chloride (PVC) Conduit. When expansion fittings are installed, they are frequently secured on the wrong end. The manufacturer’s installation instructions require the expansion fitting to be secured on the "bell" (fixed) end. Care should be taken when mounting the fitting in a vertical position as the fitting must be installed with the “bell” end above the sliding or expanding end. An example of the installation instructions for one manufacturer’s expansion fitting can be found here: Expansion-Coupling-Usage-Guide.pdf (cantexinc.com)
