You're right, that's generally the easier and safer approach. Here's a breakdown of why, and some things to consider

Why Dropping Down is Easier & Better:
Simpler Wiring

Running separate drops from the ceiling to each receptacle is typically a straightforward wire run. You're working vertically.

Less Obstructed Wiring

Columns create obstructions. Bending wire around them, securing it properly, and meeting code requirements for protection can be challenging.

Easier Access for Maintenance

If you ever need to troubleshoot or replace wiring, accessing individual drops is much easier than working around a column.

Aesthetically Cleaner

Depending on the column design, wrapping wire around it might be unsightly. Hiding the wire drop inside the wall and behind the receptacle is usually cleaner.

Code Compliance

Depending on local codes, exposed wiring (or wiring attached to a surface without proper protection) might be a violation. Dropping down inside the wall cavity usually avoids this.

Considerations for Dropping Down



Wall Cavity Access

You need to be able to get the wire down the wall cavity without obstruction. Make sure there aren't fire blocks or other obstructions in the wall.

Fishing Wire

You may need to "fish" the wire down the wall, which involves using tools to guide the wire.

Secure Wiring

Secure the wire within the wall cavity according to local code (usually with staples or other approved fasteners).

Adequate Box Fill

Ensure the receptacle boxes have enough space for all the wires entering them, as per the National Electrical Code (NEC).

Why Wrapping the Column is Problematic



Appearance

It's rarely an attractive solution.

Protection

How would you protect the wire from damage? Running conduit on the surface of the column is one option, but it changes the column's appearance.

Bending

Wires have minimum bending radii. Trying to force them around a tight corner on a column can damage the insulation and create a fire hazard.

Securing

How would you securely fasten the wire to the column? Nails or screws could damage the wire. Adhesive methods may not be reliable long-term.

Code

You may have a hard time meeting local codes in terms of protection of the wiring.

In Summary

Dropping down from the ceiling is almost always the preferred method unless there are severe obstructions in the wall cavity.

Important Safety Notes



Always turn off the power at the breaker before working on any electrical wiring. If you're not comfortable working with electricity, hire a qualified electrician. Electrical work can be dangerous and must be done correctly to prevent fire and shock hazards. Always comply with local electrical codes. These codes are in place for your safety. When in doubt, consult with a licensed electrician. Flag for review
