You've hit on a few really important points here, and it's a common struggle for many installers: balancing speed, cost, code compliance, and aesthetics. Let's break it down

Your Use Case (LFNC for Short Jumps):

Your application of LFNC for short, flexible connections is exactly where it shines. It's faster and easier than bending EMT or rigid, especially in tight spots or where movement is expected (vibrating equipment, thermal expansion). Protecting exposed PV wires around obstacles is also a valid use.

Why it Looks Tacky (and how to mitigate it)



Lack of Straight Lines and Support

LFNC naturally droops and meanders. This is the biggest aesthetic killer. Proper support is KEY. Use appropriate clamps/straps at intervals specified by the code (typically every 12 inches) and ensure it's snug but not pinching the conduit. A straight run of properly supported LFNC looks much better than a sagging, unsupported one.

Excess Length

Use only the necessary length. Long, looping runs of LFNC are unsightly. Pre-planning and careful measurement are your friends here. Cut it to the minimum required length.

Mismatched Fittings

Using the wrong type of fitting, or a fitting that's not properly tightened, will make the installation look sloppy. Make sure the fittings are rated for the conduit and are properly secured.

Color Contrast

While LFNC is usually gray, consider the color of the surface it's being mounted on. If possible, choose a closer color to the background.

General Cleanliness

Keep it clean! Wipe down the LFNC after installation to remove dirt and smudges.

Workmanship and Pride in Work

Yes, this is a HUGE factor. Even code-compliant work can look terrible if it's not done with care. Taking the extra time to: Plan the run carefully Measure accurately Support the conduit properly Use appropriate fittings Keep it clean...makes all the difference.Good workmanship always shows. It's a statement about your professionalism and attention to detail. Customers appreciate (and often pay more for) neat, clean work.

Code Considerations



Article 356 of the NEC covers Liquidtight Flexible Nonmetallic Conduit (LFNC). Pay close attention to: Support

Section 356.30 outlines support requirements. As mentioned earlier, this is critical.

Uses Permitted and Not Permitted

Make sure your application falls within the permitted uses. For example, there might be temperature limitations, or restrictions on use in specific hazardous locations.

Grounding

LFNC itself does not provide a ground path. You must ensure proper grounding of the enclosed conductors through other means (e.g., grounding wire run inside the LFNC). The Enphase cable itself does have a ground wire but make sure you terminate that ground properly at each end.

Fittings

Use only fittings listed and identified for use with LFNC.

Quality Considerations



Material

All PVC is not created equal. Buy from a reputable supplier that uses high-quality materials.

Thickness

Thicker LFNC is generally more durable and resistant to crushing and abrasion.

UV Resistance

Even though you avoid PVC for long runs, check the LFNC's UV resistance, especially if it's exposed to direct sunlight. Some LFNC formulations are more UV resistant than others.

Temperature Rating

Make sure the LFNC's temperature rating is appropriate for the environment in which it will be installed.

Alternatives



Flexible Metal Conduit (FMC)

If aesthetics are a major concern, consider FMC. It can be more expensive and requires grounding bushings, but it generally looks "cleaner" than LFNC, especially if installed with care.*

Aluminum Flex

This is another option that's gaining popularity. It's lighter than steel FMC, easier to bend, and looks better than LFNC in many situations.

Conclusion:

LFNC is a valuable tool in the installer's arsenal. It's fast, cost-effective, and flexible. However, it's essential to use it correctly, according to code, and with attention to detail. Proper support, short runs, high-quality materials, and appropriate fittings can significantly improve the aesthetics of LFNC installations. If you're still concerned about the appearance, consider alternative flexible conduit options like FMC or aluminum flex.Your pride in your work will translate into a better looking install.
