Intro to Marinas, Docks, and Boatyards:

Electrical Inspection Checklist: Marinas, Docks, and Boatyards

This Electrical Inspection Checklist: Marinas, Docks, and Boatyards is engineered to provide an NEC compliant process to guide you in your safety inspections.

Electrical inspections are always important and vital to the safety of anyone utilizing the area, but marinas, docks, and boatyards require a special degree of care given the presence of water. Wet surfaces and areas can be highly conductive and present a number of non-electrical hazards also. 

It is vital that we take great care in inspecting these areas and apply the NEC standards specific to the circumstances. 

This process is editable and you can add or remove steps as you please. Each inspection-specific task contains the relevant NEC section reference which applies to the action. 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.

You can watch the video below to demonstrate the importance of electrical safety in marinas and docks and the steps you need to take to provide environments which everyone can enjoy.

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.

Determine the applicability of Article 555

NEC: 555.1

Article 555 determines which areas qualify to be inspected under these specific conditions. 

Broadly speaking it refers to any area which is in or around water including marinas, docks, boatyards, floating piers, and wharves. Article 555 specifically refers to the installation of wiring within these spaces. 

You can find a detailed analysis of Article 555 in this PDF.

Inspect the shore power receptacles

NEC: 555.19(A)

Make sure that the shore power receptacles have an appropriate grounding type and ampere ratings. 

Use the form field below to record your notes.

Make sure general use receptacles are GFCI protected

NEC: 555.19(B) 

You need to make sure ground fault circuiter interrupters are in place for general use receptacles.

For an introduction to GFCI protection, you can read this article. Or, you can watch the video below for a discussion of GFCIs and their place within current NEC guidelines. 

Record your notes in the form field provided.

As we mentioned in the introduction, wet areas contain a higher degree of risk. As such, you must make sure all wiring is appropriate for the conditions. Make sure that portable power cables, where used, are extra-hard-usage type listed for wet locations and sunlight resistance

Make sure equipment is correctly grounded

NEC: 555.15 

Make sure equipment requiring grounding is connected to an insulated equipment grounding conductor that is included with both feeders and branch circuits.

Check all wiring over and under navigable water for clearance

NEC: 555.13(B)(3) 

Leave your notes on the wiring practices in the form field below.

Check wiring in motor fuel dispensing stations

NEC: 555.21

The wiring in motor fuel dispensing stations should be compliant with article 514. This is the relevant set of regulations governing the dispensers of flammable fuels. 

You can read more about article 514 here.

Make sure floating dock service equipment is adjacent

NEC: 555.7 

Make sure the service equipment for floating docks or marinas is located adjacent to, but not on or in, the floating structure. 

Leave your notes below.

Verify ground-fault protection for main overcurrent device

NEC: 555.3

Make sure the protection is in place for the main overcurrent device which supplies the marina. 

Leave any notes in the form field provided. 

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.
