Black is the standard color for hot wires, which transfer electricity to your outlets and switches. Red wires are also hot wires. White (and sometimes gray) wires are considered neutral, delivering power back to the panel. Finally, green wires, which are sometimes bare copper, are ground wires, used to ground an electrical circuit and prevent electrocution.

If you’re outlet isn’t working but the breaker isn’t tripped , that could mean a number of things. First, check if it’s a GFCI outlet, which has added protection so your breakers don’t malfunction. If that’s the case, simply hit the outlet's reset button and see if it works. If it doesn’t, or you don’t have a GFCI outlet, you might have a loose outlet or loose wiring, a damaged breaker, or an overloaded circuit, which would require a dedicated breaker. It’s best to consult with an electrician to diagnose the problem accurately.

The cost to replace or install an electrical outlet can vary. On average, you can expect to pay between $125 and $215 per outlet, including labor and materials. For a standard 120v outlet, the material cost is typically between $10 and $50. Labor costs for an electrician usually range from $50 to $100 per hour. The total cost can be higher if there are complex electrical issues to resolve. Specialized outlets like GFCI or high-voltage types can cost up to $50 each for the material alone. If you are replacing many outlets throughout your home, the total project cost could be between $900 and $3,000, but you may receive a better per-outlet rate from the electrician.

Burnt outlets can be caused by things such as faulty wiring, loose connections, or a circuit overload—and yes, they are extremely dangerous. If you notice your outlet is hot or has burn marks, you should shut off the power to it from the circuit breaker and immediately call an electrician.
