Anyone can handle many home improvement jobs. However, some should be left to professionals. Electrical works are perfect examples of those jobs that should only be attended to by professionals. At a time where you can learn how to do anything by yourself thanks to DIY videos, you should never be tempted to handle electrical jobs.
Safety concerns
The main reason most people are discouraged from attempting to fix any 
electrical problem is for safety reasons. As much as you might not live without electricity, it poses a real threat when handled by the wrong hands. Only a slight error can put your property to flame or you can even electrocute yourself. Electrical systems are wired differently. As such, the approach used in different situations can be entirely different. Since it requires a professional eye to see these differences, it is advisable to hire a professional for the interest of your safety and that of those close to you.
Electrical system maintenance
Maintain your electrical systems should be part of your home improvement routine. It makes all the sense to have an electrician inspecting and to make relevant adjustments to your electrical systems if need be. Again, safety is usually a primary concern when doing these type of jobs. With the pros, you can rest easy knowing that all is well.
Preventive work
Part of home improvement lies in making your home safe now and in future. As such, hiring an electrician will help you address some of the risks as well as prevent future problems. Ideally, this may be possible by identifying potential risk areas and taking the necessary measures. If you are often troubled by unnecessary tripping or short-circuiting, an electrician should be able to address any electrical issues comprehensively.
Referrals
Working with an experienced electrician comes with another benefit of getting referrals. Being in this industry, a good contractor can refer you to other professionals like a plumber and air conditioning experts. In case there is an electrical job that is beyond them, most professionals should be willing to refer you to the right people.
An electrician plays a critical role in any home improvement projects. Besides just ensuring that all electric connections, most of them can be in a position to advise and offer referrals for jobs that are beyond their scope.
