Does my switchboard bus tap need inspected?
Adding alternative electrical energy production and storage systems can provide exceptional value to your facility. Oftentimes, this requires modification to your existing equipment and systems. However, any field modification made to listed equipment, including a switchboard bus tap interconnection, as covered in NFPA-70 article 230.82, means the local Authority Having Jurisdiction (AHJ) must approve the modification to the switchboard. In most cases, the AHJ will request the installer obtain field evaluation and labeling by an accredited Field Evaluation Body (FEB) prior to approval. Most switchboards rated 600 volts and below are listed to the applicable industry electrical standards.
Evaluating the interconnection requires ensuring that the switchboard still meets the requirements of the subject electrical standards, and applicable installation codes after the interconnection has been performed. Generally, investigation of the bus tap interconnections occurs during a utility shut down of electrical power to the facility and the evaluation must be completed before power is restored to the switchboard. Clear communication of the requirements for the installation both prior to, and during, the shutdown as the installation is being made is critical for project success. eti Conformity Services’ (etiCS) compliance engineers have the knowledge, skills and experience to properly conduct field evaluation of modified switchboards to keep projects delivered on time and within budget.
