A GFCI (Ground Fault Circuit Interrupter) is a device designed to prevent electric shocks by cutting off the power if it detects a problem. Wet conditions are just one element that can lead to electric shock. When you use an extension cord with a GFCI, it can sometimes make the GFCI less effective. This happens because the extension cord can add extra resistance and potential faults, which might prevent the GFCI from working properly.
In simple terms, using an extension cord with a GFCI can make it harder for the GFCI to detect problems and shut off the power. This increases the risk of electric shock or electrocution.
- Gauge of the Cord: The gauge indicates the thickness of the wire. For a cord over 100 feet, use a 10-gauge extension cord to handle the higher electrical load and minimize voltage drop. For a length of 50 feet, a 12-gauge extension cord is suitable, as it can handle up to 18 amps. You may need a 10-gauge cord for shorter lengths depending on your machine’s current cord length.
- Outdoor Rating: Make sure the extension cord is rated for outdoor use. Look for cords labeled “SJTW” or similar, which indicates they are suitable for outdoor conditions.
- Amperage: Electric pressure washers typically require around 15 to 20 amps. Ensure the extension cord can handle this load. A 10-gauge cord typically supports up to 15 amps comfortably.
