Do power supplies need a safety standard?

While one would expect that a safety standard for power supplies would be dominated by consideration of electrical hazards, this is not the only aspect of power supply design affected. A more complete listing of safety issues could include the following:

Do I need a GFCI outlet if I run power outside?

When running power outside, a GFCI-equipped outlet is required by code in all areas exposed to moisture, such as the outdoors, and ensures safety. When adding an outdoor outlet, be sure to choose an outdoor-rated, weatherproof model with built-in, high-sensitivity GFCI.

Is a permanent power outlet necessary?

For lighting, lawn tools used on a regular basis, or power needs for outbuildings, you need a permanent power solution for safety. This can involve an outdoor outlet addition to your home's main structure, or wiring run remotely to an outbuilding.

How can you ensure a power cord's safety?

To ensure safety and prevent tripping hazards, select a power cord with TEST/RESET buttons, typically found in kitchens, baths, and garages, which protect your family from shock in the event the cord is exposed to water. Be sure to choose a cord that is the correct length, neither too short nor too long.

Is a permanent power solution necessary?

For lighting, lawn tools used regularly, or power needs in outbuildings, a permanent power solution is necessary for safety. This can involve adding an outdoor outlet to your home's main structure or running wiring remotely to an outbuilding. For power lines not connected to your house, cable must be wired to a separate GFCI indoors.

How do I choose an outdoor outlet?

When choosing an outdoor outlet, be sure to select an outdoor-rated and weatherproof model with built-in, high-sensitivity GFCI\. All exterior outlets should have spring-loaded covers to protect them from weather, pests, and most importantly, moisture.
