Okay Brian, let's tackle this 230.62(C) issue. You're right, it's not a super common thing you encounter all the time.

Understanding 230.62(C)

First, let's be crystal clear on the code: NEC 230.62 Protection Against Damage. (C) Enclosures for Service Equipment. Where an enclosure for service equipment has a hinged cover that is capable of being opened without disconnecting the power, the enclosure shall be provided with a barrier to prevent any loose uninsulated conductors from contacting the enclosure.Basically, if you can open the cover of your service disconnect with the power still on (which you usually can with a QO disconnect), and there are exposed, uninsulated conductors inside that could potentially touch the enclosure, you need a barrier. This prevents accidental contact and potential short circuits.

Why You're Having Trouble Finding a Specific Part

The reason you're likely struggling to find a specific "rubber guard" or "barrier" listed for your specific Square D QO outdoor disconnect is that manufacturers don't always provide a one-size-fits-all solution for this. The method of compliance can vary.

Possible Solutions and Approaches


Square D Documentation (First Check)

Before doing anything else, look very carefully at the Square D documentation (installation instructions, parts list, etc.) that came with your disconnect. They might have a recommended barrier or a specific part number for one. It could be a small plastic piece that snaps in. Check Square D's website or call their tech support.2.

Universal Barriers/Insulating Sheets



Electrical Supply Houses

Ask your electrical supply house if they have any universal insulating barriers/sheets that can be cut to size. These are typically made of a tough, non-conductive plastic or fiber material. You'd cut it to fit inside the enclosure to provide the needed protection.

McMaster-Carr or Similar Suppliers

Companies like McMaster-Carr carry a wide range of electrical insulating materials that could be used to fabricate a suitable barrier.3.

Fabricated Barrier (Carefully Considered)

You can fabricate a barrier yourself, but it

must be done properly. Use a listed, non-conductive material suitable for electrical applications (e.g., a polycarbonate sheet, phenolic material, or other approved insulator). Make sure it's securely fastened (e.g., with non-metallic screws or standoffs) so it can't come loose and potentially cause a hazard. The barrier should effectively block access to any uninsulated conductors on the line side when the cover is opened. Double-check with your inspector before going this route. They may have specific requirements or preferences for fabricated barriers.4. Relocation of the line side conductors You may be able to use proper spacing to position the conductors as to make it impossible for the un-insulated conductors to come into contact with the enclosure.

Important Considerations



Professional Appearance

Whatever solution you implement, it should look professional and well-executed, not like a sloppy afterthought.

Safety First

Make sure any work you do is done with the power OFF (safely de-energized and verified).

Ask the Inspector

This is often the best approach. POLITELY ask the inspector what specifically they are looking for and if they have any suggestions for acceptable solutions. They may have seen this situation before and can offer helpful advice. It's much better to get their feedback before* you implement a solution.

Troubleshooting Steps


Re-Read the Documentation

Go back through the Square D documentation one more time.2.

Contact Square D Tech Support

Call Square D's technical support line and explain the situation. They may have a solution or be able to provide guidance.3.

Talk to Your Electrical Supply House

Explain the issue and see if they have any universal barriers or suitable insulating materials.4.

Talk to the Inspector: Explain that you're having trouble finding a specific part and ask for their advice and acceptance of various potential solutions.Good luck, Brian! It might be a little frustrating, but you'll get it sorted out. Just focus on providing a safe and code-compliant solution. Flag for review
