CordSafe PLUS — Frequently Asked Questions

CordSafe PLUS is a weatherproof snap-on safety cover that protects outdoor extension cord plug connections from rain, snow, moisture, and UV exposure. Below are answers to the most common questions about how CordSafe PLUS works, where it can be used, and how it compares to other outdoor cord protection options.

General Questions

What is CordSafe PLUS?

CordSafe PLUS is a snap-on weatherproof cover that seals the plug connection between two outdoor extension cords, or between a cord and a device. It is made from UV-resistant, BPA-free polypropylene, installs tool-free in seconds, and is reusable season after season. Made in USA.

How does CordSafe PLUS work?

Connect your extension cord plugs as normal, then snap CordSafe PLUS over the connection. Its internal plug insulator and UV-resistant polypropylene shell seal the joint against rain, snow, moisture, and accidental disconnection. No tools, tape, or zip ties required. 

What cord gauges does CordSafe PLUS fit?

CordSafe PLUS fits 12–18 AWG outdoor extension cords, covering the full range of cords used for holiday lighting, patio string lights, pool pumps, power tools, and outdoor equipment.

Is CordSafe PLUS waterproof?

CordSafe PLUS is weather-resistant and designed to protect plug connections from rain, snow, and moisture. It is not rated for submersion.

Is CordSafe PLUS reusable?

Yes. CordSafe PLUS is designed to be removed, stored, and reused season after season. It is available in 2-pack, 10-pack, 20-pack, and 100-pack options.

What colors does CordSafe PLUS come in?

CordSafe PLUS is available in White, Black, Green, Orange, and Red.

Where is CordSafe PLUS made?

CordSafe PLUS is Made in USA from UV-resistant, BPA-free polypropylene.

Is CordSafe PLUS BPA-free?

Yes. CordSafe PLUS is made from BPA-free food-safe polypropylene.

Holiday Lighting

How do I protect outdoor Christmas light cord connections from rain?

Snap CordSafe PLUS over the plug connection between your extension cord and string lights. It seals the joint against rain, snow, and moisture — the leading cause of holiday light failures and tripped GFCI outlets.

Can I leave CordSafe PLUS outside all holiday season?

Yes. CordSafe PLUS is UV-stable and weather-resistant, making it suitable for continuous outdoor exposure throughout the holiday season.

Can CordSafe PLUS prevent GFCI trips from outdoor Christmas lights?

Yes. Moisture at plug connections is a leading cause of nuisance GFCI trips. CordSafe PLUS seals the connection, reducing moisture intrusion and the likelihood of trips during peak use.

Does CordSafe PLUS work with outdoor inflatables?

Yes. CordSafe PLUS fits 12–18 AWG extension cords and is ideal for protecting plug connections on outdoor inflatables, timers, and other seasonal decorations. Check the inflatable plug connection, some MAY NOT fit.

What is the most common cause of outdoor holiday light failures?

Moisture intrusion at the plug connection is the most common cause. Rain, dew, and snow can cause short circuits, tripped GFCI outlets, and complete light failures. CordSafe PLUS seals this connection before failure occurs.

Patio & String Lights

Can CordSafe PLUS be used with patio string lights and bistro lights?

Yes. CordSafe PLUS fits 12–18 AWG extension cords and is ideal for protecting plug connections on patio string lights, bistro lights, and outdoor Edison bulb strands.

How do I keep patio string light connections from getting wet?

Snap CordSafe PLUS over every plug connection in your patio lighting setup. It seals the joint against rain, dew, and moisture — the leading cause of outdoor string light failures.

What extension cord do I need for patio string lights?

Use an outdoor-rated extension cord with a minimum 16 AWG gauge for standard string lights. For longer runs or higher wattage, use 14 or 12 AWG. Protect every connection with CordSafe PLUS.

Pool Pump Use

Can I use an extension cord with my pool pump?

Yes, but only with the correct gauge outdoor-rated extension cord — typically 12 AWG for runs up to 25 feet. Connect to a GFCI-protected outlet and protect the plug connection with CordSafe PLUS to prevent moisture intrusion.

What gauge extension cord do I need for a pool pump?

Most residential pool pumps require a 12 AWG extension cord for runs up to 25 feet. For longer runs, use a 10 AWG cord. Always check your pump’s amperage rating and match the cord gauge accordingly.

Does a pool pump need a GFCI outlet?

Yes. The NEC requires GFCI protection for all pool pump motors. If your outlet is not GFCI-protected, use a GFCI extension cord or have a licensed electrician install a GFCI outlet.

Why does my pool pump keep tripping the GFCI?

Common causes include moisture at the plug connection, a failing pump motor, a damaged cord, or a faulty GFCI outlet. Protect the plug connection with CordSafe PLUS to eliminate moisture as a cause.

How long can an extension cord be for a pool pump?

Keep runs under 25 feet with a 12 AWG cord. For longer runs, use a 10 AWG cord to minimize voltage drop and prevent motor overheating.

Farm, Ranch & Outdoor Equipment

Can CordSafe PLUS be used with heated pet water bowls, bird baths, and heated mats?

Yes. CordSafe PLUS protects the plug connection between your extension cord and heated pet equipment or bird bath heaters, preventing moisture intrusion that can cause shorts or tripped breakers.

Can CordSafe PLUS be used in barns and outbuildings?

Yes. CordSafe PLUS is designed for any outdoor or semi-exposed environment, including barns, sheds, and outbuildings where extension cord connections are exposed to moisture and dust.

Comparisons

What is the difference between CordSafe PLUS and a Twist and Seal or FLemoon cord cover?

CordSafe PLUS snaps over the plug connection and uses an internal insulator to seal the joint. Twist and Seal covers wrap around the cord body. CordSafe PLUS targets the plug connection point — where outdoor electrical failures most commonly occur.

Is CordSafe PLUS better than electrical tape for outdoor cord connections?

Yes. Electrical tape degrades in UV and moisture over time and leaves adhesive residue. CordSafe PLUS is a reusable, UV-resistant polypropylene cover that provides consistent weatherproof protection without tape.

Why do outdoor extension cord connections fail so often?

Most failures happen at the plug joint — where two cords meet or where a cord connects to a device. Rain, moisture, thermal cycling, and physical stress all degrade this connection. CordSafe PLUS seals and stabilizes the joint before failure occurs.

Winter Use

Can CordSafe PLUS be used in freezing temperatures?

Yes. CordSafe PLUS is made from UV-resistant polypropylene that maintains its properties in cold weather, making it suitable for winter outdoor use.

Why do outdoor extension cord connections fail in winter?

Cold temperatures make cord insulation brittle, and freeze-thaw cycles cause plug connections to loosen. Moisture from snow and ice at the plug joint causes shorts and tripped breakers. CordSafe PLUS seals the connection against winter weather.
