Electrical Inspection Checklist: Electric Vehicle Charging Equipment

This Electrical Inspection Checklist: Electric Vehicle Charging Equipment is engineered to provide an NEC compliant process to guide you in your safety inspections.

Electric vehicles are an increasingly popular form of transports and have seen both established manufacturers leaning toward them, while new emergent companies like Tesla also gain notoriety.

Electric cars are very powerful and, on a full charge, contain a large amount of energy. As such, it is important that we are able to provide a safe experience for users of electric cars. The first step to providing that is being able to maintain the equipment with effective inspection processes. 

This template is malleable and you can add or remove steps or detail within each step as you please. Each inspection-specific task contains the relevant NEC section reference to contextualize the advice and provide a greater opportunity to see how the process relates to the source material. It is recommended that you familiarize yourself with the standards before beginning any inspection

Throughout the checklist, you will find form fields where you can record relevant information. This data will be stored in the template overview which you can view on the left-hand tab for the template. You can export this data for review to provide an overview into your inspections. 

If you utilize the form fields well, you can select to print your checklist which will give you the option to save it as a PDF. This can, therefore, act as a report generator which you can save and then send to the relevant stakeholders once your inspection is completed.

Watch the video below to get an idea of how an inspection would work. This video shows the inspection process for a Nissan Leaf.

Record inspection details

Use this section to record the key details of the inspection.

Enter your information into the form fields provided. 

Run general inspection safety checklist

An electrical inspection is normally needed to ensure the safety of others. However, it is important to make sure that your own safety is not put at risk in performing the inspection. 

You can find here our checklist for making sure you are safe before performing your inspection

Electrical Inspection Checklist

The first half of this checklist is designed to help you assess the area and risk in order to do your job safely and well. 

We recommend you run this checklist before starting any inspection.

Make sure all equipment, devices, and fittings are listed

NEC: 625.5 

Make sure everything is accounted for and present. If certain elements of equipment are missing, this can lead to problems with protection or other safety concerns.

Use the form field below to leave your notes.

Check the condition of the electric vehicle coupler

NEC: 625.10 

The coupler is a key movable part in the charging process. As such, it can be exposed to greater risk of damage or wear. Make sure the coupler is suitable for the job and that its condition meets safety standards.

Make sure coupler and cable safeguards have been provided

NEC: 625.18, 625.19

Check that safeguards are in place or provided for the charging equipment. 

Leave your notes in the form field provided. 

Verify the rating of branch-circuit and feeder overcurrent devices

NEC: 625.40, 625.41

Make sure the ratings meet required standards.

You can read more about feeder overcurrents and their protection and equipment practices at ECMWeb.

You can leave your notes in the space below. 

Check for the provision of a personnel protection system

NEC: 625.22 

It is always important to prioritize personnel safety when conducting checks and inspections. Make sure the protection system in place is adequate and sufficient to meet the demands placed upon it.

Check the location of disconnecting means

NEC: 625.42

Given that electric vehicles are very energy intensive pieces of equipment, the charging process utilizes a great deal of energy. For this reason, it's of vital importance to have adequate disconnecting means available. 

Check the location of disconnecting means rated over 60 amperes or 150 volts to the ground.

Make sure there are backfeed prevention provisions

NEC: 625.46, 625.48 

When charging an electric vehicle, we want to make sure power is only heading in one direction. Our backfeed prevention set up will help provide that there is no risk of reversed voltage polarity. 

Make sure the charging equipment is able to provide these suitable protections

Record location and height of charging equipment

NEC: 625.50

You can use the form fields below to record the location and height of the charging equipment. 

Assess the ventilation needs for any indoor charging equipment

NEC: 625.15, 625.52

It is important to make sure that the location has been properly assessed for its ventilation needs. If ventilation is required then it should be in place, and the ventilation potential of the location should be held to an appropriate standard. 

Electric cars may be cleaner than the gas guzzling counterparts, but well-ventilated charging areas should still be maintained.

Write down overall notes regarding inspection

If you have any other thoughts or comments which you would like to include in your report, leave them in the form field provided. 

Send report via email to key stakeholders

You can use the email widget to send a copy of your report to the key stakeholders. 

The information from your first task is being pulled into the body of the email through the use of variables. You can find more about variables on our help site
