Why use an Electrician?
While using a professional isn't the cheapest on budgets, people typically don't realize their own safety is at risk. Think about it - would you see a heart doctor to check out your kidney, rotator cuff or dental related issue? No way! We get asked or hear a lot of people say "I'll replace outlets myself to save money" or "my painter installed a light" or "my kitchen guy installed cabinets and installed my recessed lighting"...meanwhile the microwave is on a circuit with lower capacity than it should be, on the same circuit with the lights, and the kitchen has no GFI outlets on the counter tops.
Or for example, a bathroom is renovated and the old 15 amp bathroom circuit that's tied in with the garage and exterior outlets was NOT upgraded to the current code standard of a 20 amp dedicated circuit. And the most terrible part is that the client has no idea how unsafe this type of installation is. In fact, as shown in the pictures below, the majority of the time a non-licensed person does an installation incorrectly and it's full of safety hazards, etc. It's not only just an unsafe installation, it's now an insurance compliance issue as well. There are very many nuisances when doing electrical work and most general people are not aware about circuit loads or grounding or other types of code compliant situations.
All in all, we highly suggest that you please do not let an unlicensed person touch any of your electrical system. Period. They might get something to "work" and it might be a fraction of the cost of a licensed professional, but "working" condition doesn't always mean code compliance nor safety. We've seen it happen time and time again - an unqualified person installs an outlet and there's no safety ground, or a subpanel is wired wrong or a switch or outlet has no box, etc. At the end of the day, our clients end up paying more to correct existing issues.
While it may seem easy at first appearance, there's a lot of knowledge that goes into just replacing an outlet - such as outlet type, requirements in spacing, loading. If these efforts are not followed, you are in a safety hazard such as a shock potential, fire or component damage situation. Nevertheless, a very upsetting situation for us and it's the last thing we want to see our clients experience.
