If your outlet needs to be reset multiple times, you likely have a problem with the outlet, the reset button, the wiring, or its connected circuit breaker. If the reset button doesn’t work and the circuit breaker isn’t the issue, it’s likely a problem with the outlet or the reset button it’s attached to.

If you strictly adhere to electrical safety rules, including assuming that a circuit is hot until proven otherwise, and have some knowledge of how an electrical circuit works, you can likely replace a light switch by yourself without too much trouble. However, it's always advisable to call a nearby electrical pro to do the job if you're unsure of any steps necessary to change a light switch. 

To check if doorbell wires are live, use a non-contact voltage tester. Hold the tester near the wires; if it lights up or beeps, the wires are live. Always ensure the power is off at the breaker box before handling any wiring. If you don't have a voltage tester, consider getting one or consulting a professional to ensure safety.

Aluminum wiring can pose a significant fire risk because it tends to expand, contract, and overheat, leading to failing connections and splices. If your home has aluminum wiring, it doesn't always require a complete replacement, but you must take safety precautions. The first step is to hire a licensed electrician to conduct a thorough inspection. Based on their findings, you have several options:

• Full Replacement: The safest but most expensive solution is to replace all aluminum wiring with copper.

• Copper Pigtailing: A more budget-friendly option, suitable for certain homes, involves adding a short section of copper wire to the end of each aluminum wire at connection points.

• Other Safety Upgrades: Your electrician may also recommend installing aluminum-compatible outlets and applying an anti-oxidant paste to connections to prevent corrosion.

Consulting a professional will help you determine the best course of action to ensure your home's wiring meets current safety standards.
