The Electrical Safety Foundation (ESFI) recently surveyed building owners and managers to gauge their understanding of electric vehicles (EV) and the safe installation of electric vehicle supply equipment (EVSE), or EV charging stations and chargers. The goal of the survey was to identify safety gaps related to emerging technology to keep consumers, installers, and businesses safe. The survey results showed that over 91% of building owners had a site inspection conducted before installing EVSE.

Survey respondents stressed the importance of having the equipment installed professionally, with high-quality equipment, to ensure all measures meet standards for safety and code compliance. “To prepare your building for EV charging, it’s imperative to have a qualified electrician complete an electrical system inspection to ensure your business has the right electrical capacity for EV charging,” said ESFI President Brett Brenner. “All EV charger installations and site inspections should only be completed by qualified electricians who have been trained and are insured and bonded to complete electrical work.”

Many respondents advised thoroughly researching and planning before installing EVSE. Several respondents recommended taking the time to install EVSE properly, as the process can take longer due to permitting or the availability of parts. Of the building owners who were surveyed, 46.5% had to have maintenance conducted on their EVSE, while 19.8% had to replace EVSE equipment. Of those that had to replace equipment, 23.5% replaced cables, 19.6% replaced plugs or connectors, 17.6% replaced electronic components or control units, 15.7% replaced housing or enclosures, and 11.8% replaced ground fault circuit interrupters.

Overall, 89% of survey respondents were satisfied or very satisfied with their EVSE installation ex
