Electricians Services:
Electricity is essential for light, power, air-conditioning, and refrigeration. Electricians install, connect, test, and maintain electrical systems for a variety of purposes, including climate control, security, and communications.
They also may install and maintain the electronic controls for machines in business and various industries. Maintenance electricians working in factories, hospitals, apartments and other settings repair electric and electronic equipment when breakdowns occur and install new electrical equipment. When breakdowns occur, they must make the necessary repairs as quickly as possible in order to minimize inconvenience. They may replace items such as circuit breakers, fuses, switches, electrical and electronic components, or wire. Electricians also periodically inspect all equipment to ensure it is operating properly, and locate and correct problems before breakdowns occur.
Electricians also advise management whether continued operation of equipment could be hazardous. When working with complex electronic devices, they may work with engineers, engineering technicians, line installers and repairers, or industrial machinery installation, repair, and maintenance workers.

Plumbers and pipe fitters assemble, install, and make changes in pipe systems used to carry water, steam, air, and other liquids and gases. They install plumbing fixtures, such as bathtubs and toilets. They also install heating and refrigeration units. Plumbing and pipe fitting are generally considered to be separate trades, though many qualified craft workers are skilled in both fields. Plumbers and pipe fitters use many tools, including benders, wrenches, drills, reamers, chisels, hammers, and other hand tools. They also use gas or acetylene torches and welding and soldering equipment for their work.
