This guide explains how to identify the correct outdoor extension cord for a Snow Joe® or Sun Joe® corded electric product. Extension-cord requirements can vary by model, including permitted length, minimum wire gauge (A.W.G.), plug configuration, and connection method. Some models allow extension cords up to 100 ft, with a heavier wire gauge required for longer cords. Corded pressure washers have a separate requirement. Always check the exact-model manual before selecting or connecting an extension cord.
SWJ803E Example:
Choose the Correct Extension Cord
- Confirm the exact model number.
Check the product label, packaging, order information, or manual. - Open the exact product manual.
Do not use a manual for a similar-looking product or another model in the same family. - Find the extension-cord chart.
It is commonly located in the electrical-safety information near the beginning of the manual. - Match both cord length and minimum wire gauge.
Follow the chart for the total extension-cord length you plan to use and select a cord that meets the stated minimum A.W.G. - Check the plug and connection requirements.
Confirm that the extension cord matches the plug configuration and electrical requirements stated in the exact-model manual. - Confirm the cord is approved for outdoor use.
Follow every rating, connection, and maximum-length requirement stated in the manual. - Check how the cord should be secured.
If the product uses a cord restraint or cord-retention system, follow the routing and connection instructions in the exact-model manual. - Inspect the cord before use.
Do not use a damaged cord, plug, receptacle, or connection.
Cord Length + Wire Gauge
Customers often need help determining whether a particular cord length or gauge can be used with their product. The correct requirement depends on the extension-cord chart in the exact-model manual.
| Extension Cord Length | Minimum Wire Gauge (A.W.G.) |
|---|---|
| Up to 50 ft (15 m) | 14 A.W.G. |
| More than 50 ft up to 100 ft (15 m – 30 m) | 12 A.W.G. |
Plug + Connection Requirements
Extension cords can use different plug and receptacle configurations. Before connecting a cord, compare the product's plug and electrical requirements with the instructions in the exact-model manual.
- Check the product plug.
Review the exact-model manual and the product connection before selecting an extension cord. - Use the required plug configuration.
Use an extension cord that matches the connection and ratings specified for your product. - Never modify the connection.
Do not remove, bend, alter, or bypass a prong or modify an extension-cord connector to make it fit. - Confirm the connection is secure.
If the connection does not fit properly or will not remain secure, stop and review the exact-model manual before operating the product.
Extension-Cord Restraint + Connection
Some corded products use an extension-cord restraint or cord-retention system to help keep the extension cord secured during operation.
- Locate the cord-restraint instructions.
Check the manual for your exact model for the applicable illustration and routing instructions. - Route the cord exactly as shown.
Cord-restraint designs can vary between products, so do not copy the routing method from another model. - Check the connection before operation.

Additional Guidance
Why Requirements Differ by Product
Electric products can have different power demands and electrical designs. Their manuals may therefore specify different maximum cord lengths, minimum wire gauges, plug configurations, or connection methods.
Use the product-specific information instead of a general recommendation.
What If I Cannot Find the Extension-Cord Chart?
Confirm that you have the manual for the exact model, then check the electrical-safety pages near the beginning of the manual.
Do not guess the cord size or borrow a recommendation from another model.
Models That Allow Up to 100 ft
Some models use a chart that permits up to 50 ft with 14 A.W.G. and more than 50 ft up to 100 ft with 12 A.W.G.
For models using this chart, do not exceed 100 ft. Always confirm that your exact-model manual contains this requirement before using these values.
Corded Pressure Washer Requirements
For a corded pressure washer, use only a 14-gauge outdoor extension cord up to 25 ft maximum.
Using a Third-Party Extension Cord
Use only a cord that meets every rating, length, minimum-gauge, plug-configuration, and outdoor-use requirement stated in the exact product manual.
Inspect the cord and connectors before each use.
Extension Cord Will Not Stay Connected
Check whether your product uses a cord-restraint or cord-retention system and follow the exact-model manual for the proper routing method.
Inspect the plug, receptacle, cord, and restraint area. Do not use the product if the connection is damaged, loose, or cannot be secured as instructed.
