There has been a fantastic metamorphosis in the electrical equipment both in the home appliances, small-scale business, and industrial 
sectors. These milestones applied by electrical contractors are hand in hand with millennium development goal, and the sustainability of the already strained energy sector by the ever-growing population which is now at 7 billion in the world. Most fundamentally, the advancements in the electrical equipment center around the ability to improve the maintenance especially in massive repairs intervals and to enhance efficiency in the general productivity of the gadgets set up by the electricians.
Preventive and Maintenance Programs
A good electrician should make sure that all the electrical appliances are at the top of maintenance and timely repairs to reduce the risks that come with it.
One of the best ways is to download a mobile app that will be a reminder on where and how the electrical equipment needs attention. The electrical contractor will feed all the data including the geographical locations and the nature of repairs required in finer details in the app.
Efficiency
In the quest to improve the equipment, alternative methods of providing energy have been at the peak. Shannon Yee, an Assistant Professor 
in Georgia Tech’s (school of mechanical engineering), has developed Na TECC. The technology leverages Isothermal expansion of Sodium and solar heat to generate electricity directly. This engine can run the entire house without involving other sources like biomass and spinning turbines. Many electrical contractors across the world have adopted this technology.
Flexibility
The modern electrical equipment preferred by many electricians are the ones that adapt well to zero emissions. It’s not only healthy to use them but also cost-effective and efficient. For instance, having equipment that has combustion systems which can burn gas of different compositions is a plus. Most of these zero emissions equipment is powered by the windmills, biomass, renewable, and microgrid systems. Wireless power transmissions will soon be all over the world after completion of the phases of research, and testing.
Generally, the technological advancements have resulted in developing electrical equipment that is cost-effective, efficient and flexible. Every electrician today matches his/her expertise by adjusting to the top-notch maintenance and repair programs.
