Okay, let's tackle this outdoor pendant light rewire. Finding the right cord for a chain-threaded outdoor fixture can be tricky, but it's definitely doable. Here's a breakdown of what to consider and the types of cord you should be looking for

Key Considerations:
Outdoor Rating

Absolutely crucial. The cord MUST be rated for outdoor use (sunlight, water, temperature fluctuations).

Gauge (Wire Thickness)

Match or exceed the gauge of the original cord. For most residential lighting, 18 AWG (American Wire Gauge) is common, but check the original. Thicker gauges can handle more current and are safer, but are also harder to thread. If you're unsure, go one size thicker.

Insulation Type

This is the most important and tricky part. Standard indoor lamp cord will degrade rapidly outdoors. Look for insulation specifically designed for outdoor use.

Flexibility

The cord needs to be flexible enough to thread through the chain links. Stiff, rigid wire won't work.

Color

Consider if you want to match the original color or use something that blends well with the chain or fixture. Black or dark brown are common choices.

Safety Listing

Look for a UL (Underwriters Laboratories) listing or similar certification (ETL, CSA). This ensures the cord has been tested for safety.

Strain Relief

Ensure proper strain relief at the point where the cord enters the fixture and at the point where it exits the ceiling canopy. This prevents strain on the wire connections.

Suitable Cord Types (Prioritized)


SPT-2W Outdoor Lamp Cord

This is likely your best bet.

What it is

SPT-2W is a type of parallel cord (two conductors molded together) specifically designed for outdoor lighting applications. The "W" designates it as weather-resistant.

Advantages

Widely available, relatively flexible, UV resistant, moisture resistant, and usually UL listed for outdoor use. It is typically rated for 300 volts, which is standard for most lighting fixtures.

Where to find it

Home improvement stores (like Lowe's, Home Depot), electrical supply stores, and online retailers (Amazon, specialty lighting suppliers). Search for "SPT-2W outdoor lamp cord" or "outdoor lighting wire."

Considerations

It can be a bit thicker than standard lamp cord, so make sure it will fit through the chain.2.

Wet Location Flexible Cord (e.g., SJOOW, SEOOW)



What it is

These are heavy-duty, round, flexible cords with multiple layers of insulation, specifically designed for harsh outdoor conditions. SJOOW and SEOOW are common types; the letters indicate the insulation type, voltage rating, and oil/water resistance.

Advantages

Extremely durable, water-resistant, oil-resistant, and can handle a wide temperature range. Often used for power tools and outdoor equipment.

Disadvantages

More expensive than SPT-2W. Can be too thick and inflexible for threading through a decorative chain. May look industrial and not aesthetically pleasing.

When to use

If the fixture is in a very exposed location (e.g., near saltwater, subject to constant moisture) and you need maximum durability. Also use if the wattage of the light is high.

Important

Check the voltage and amperage rating to ensure it is sufficient for your fixture.3.

Underground Feeder (UF) Cable



What it is

UF cable is designed for direct burial and is extremely durable.

Advantages

Very resistant to moisture, sunlight, and physical damage.

Disadvantages

Stiff and inflexible. NOT suitable for threading through a chain. Also, it's typically larger gauge (e.g., 14/2 or 12/2) and designed for higher-current applications. This is generally overkill for a pendant light.

DO NOT USE THIS FOR THREADING THROUGH CHAIN. It is designed for direct burial, not for flexible applications.

Steps to Take


Inspect the Existing Cord

Carefully examine the old cord for its gauge (printed on the insulation) and any markings that indicate the type of insulation. This will help you choose the correct replacement.2.

Measure the Length

Determine the length of cord you need to run from the ceiling junction box, through the chain, and to the fixture's wiring terminals, plus some extra for connections. Err on the side of caution and buy a little extra.3.

Check Chain Link Size

Measure the internal diameter of the chain links to ensure the cord you choose will fit.4.

Purchase the Cord

Get the appropriate length of SPT-2W outdoor lamp cord (or the appropriate wet-location cord if needed).5.

Turn Off Power



VERY IMPORTANT! Turn off the circuit breaker that controls the pendant light before you begin any work. Double-check with a non-contact voltage tester to ensure the circuit is dead.6. Disconnect the Old Cord

Carefully disconnect the old cord from the wiring terminals in the fixture and the ceiling junction box. Take pictures of the wiring connections before you disconnect them to help you remember how to reconnect the new cord.7.

Thread the New Cord

Carefully thread the new cord through the chain links. This may require some patience. You can use a piece of stiff wire or a fish tape to help guide the cord through.8.

Reconnect the Wiring

Reconnect the new cord to the wiring terminals in the fixture and the ceiling junction box, matching the connections you photographed earlier. Use wire connectors (wire nuts) that are appropriate for outdoor use (silicone-filled).9.

Secure Strain Relief

Ensure proper strain relief at both ends of the cord.10.

Test the Fixture

Turn the circuit breaker back on and test the fixture to make sure it works.

Important Safety Tips



Work in Dry Conditions

Never work with electrical wiring in wet or damp conditions.

Wear Safety Glasses

Protect your eyes from debris.

If in Doubt, Hire an Electrician

If you are not comfortable working with electrical wiring, hire a qualified electrician to do the job. It's always better to be safe than sorry.

Local Codes

Be sure to comply with all local electrical codes.*

GFCI Protection: Ensure the circuit powering the outdoor light is protected by a Ground Fault Circuit Interrupter (GFCI). This is a crucial safety measure for outdoor electrical installations.Good luck with the rewiring! I'm here if you have more questions. Flag for review
