How hard can it be?Harder than it looks.
A switch or receptacle may look simple from the room. Behind the wall, compatibility, conductor condition, circuit design, box fill, grounding, and previous alterations can change the job completely.
The hidden part
The device is only one piece of the circuit.
The outlet, switch, dimmer, or fixture must be compatible with its load and connected to conductors and protection sized for the circuit. Smart controls can add neutral, grounding, load-type, multi-location, and enclosure-space requirements that are easy to miss.
A device that appears to work can still have a loose connection, damaged conductor, improper splice, or incorrect protection. Successful operation is not proof of a safe installation.
Troubleshooting
Previous changes can hide the real fault.
When someone changes several connections without documenting the original condition, the next person must trace both the initial problem and the new alterations. That can increase diagnosis time and make hazardous conditions harder to recognize.
If you open a box and the wiring is damaged, crowded, unfamiliar, or inconsistent with the instructions, stop, make the area safe, and call a qualified electrician.

Warning signs deserve professional attention.
Repeated breaker trips, buzzing, arcing, heat, discoloration, burning odors, shocks, flickering under load, or damaged insulation are not normal. Do not keep resetting a breaker or replacing devices to see whether the symptom disappears.
- Never work inside energized service or panel equipment
- Do not increase breaker size to stop tripping
- Use listed devices that match the circuit and connected load
- Have additions and repairs inspected when permits or local rules require it
