Permit For Charging station

Compliance with the following permit will allow the construction and operation of electric vehicle charging

station at a residence in the _____

____________ jurisdiction. Th is permit addresses the following

situations:

1. O nly a branch circuit and meter would be constructed at the residence

or
2. A hard

NFPA 70, Article 625 Electric Vehicle Charging Station s.

T h is permit contains a general reference to the NEC or electrical code used in the jurisdiction . A ll work

and inst alled equipment will comply with the requirements of the NEC or the electrical code used in the jurisdiction. The jurisdiction maintains the authority/responsibility to conduct any inspections deemed necessary to protect public safety, however due to the p rojected PEV volume it is suggested for consideration that a qualified electrician be approved to self

- inspect the system enabling system operation in advance of jurisdiction inspection.

. Th e charging station installer shall also be responsible for notify ing or coordinating any work with the utility company where needed.

Section 1 of the permit application requires basic identifying information be submitted. Note that there is a separate portion of the form requesting information on the property owner wh o may not be the individual requesting the installation.

Section 2 of the permit application identifies which code needs to be complied with depending on whether

a branch circuit and meter or a hard

- wired charging station is being installed.

The techni cal installation requirements address the following specific elements of electric vehicle charging

station safety:

A. Listing and labeling requirements

B. Wiring methods

C. Breakaway requirements

D. Overcurrent protection

E. Indoor siting

F. Outdoor siting

This permit package also includes a schematic drawing depicting a typical indoor installation. In this installation the wiring path follows the exterior of the structure and the charging station is located indoors.

The NEC ® allows for interior wiring and outdoor installations. The purpose of the schematic is only to

show how the charging station equipment could be arranged and is not intended to convey any permit requirements.
