Now that you know the steps and precautions you should take, let's talk about what you should avoid. Or in other words, the Don'ts. Some of the common Don'ts are as follows:

Work with Live Currents

This one is one of the most obvious things to avoid during your repair session. You must not work with live currents. If you choose to work with live currents, a small mishap can result in a large disaster.

Use Damaged Tools

Another mistake you should avoid is using damaged tools. Electricity is a dangerous thing by itself, and working with damaged tools increases the risk. Therefore, always work with proper tools and replace any damaged ones immediately. 

Ignore Warning Signs

Another entry on our list of "things you must not do" is ignoring the warning signs. Check out the electrical circuit immediately if you see signs such as flickering lights, tripping circuit breakers, or burning smells. These are generally the signs of an electrical problem. 

Mix Wire Types

Mixing wire types is a common mistake used by newbie DIY electricians. However, it is also one of the things you must avoid. Doing this can lead to electrical issues. Therefore, you should always avoid connecting different types of wire, such as aluminum and copper, without proper connectors. 

Work in Wet Conditions

Another one on our list of things you must not do is working in wet conditions. Most conditions can make the air a good conductor of electricity. Therefore, avoid using any form of electricity in most conditions whenever possible. Even if you have to do so, always ensure that there is no flow of electricity. Naturally, this also includes working with wet hands and working without using proper insulating gloves.

These are some of the things you must not do when repairing your electrical circuit.
