The purpose of a conduit is simple: it is a hollow vessel designed to safely carry wiring from one point to another point where it will not come into contact with a live circuit. It makes no difference whether the conduit is a metal tube or plastic pipe; its function is the same. It is simply used to carry conductor wiring from one place where it needs to be protected from contact with a live circuit to the next such as from a disconnect switch in a building’s electrical circuit or from an exterior access in a home.
In the past, and still used today, a metal conduit was the most common construction used by plugging the wires manually from a metal junction box with overhead springs powering the breakers.Today, conduit comes in various styles, sizes and colors. It comes in a variety of metal material, glass-like monolithic solid plastic conduit, fabricated from flexible material and flexible duct, and structural metal hollow tubing composed of the cap. Based on their purpose, price, and length, different types and brands are used by different electricians.
Our most used electrical gadgets – computers, television, kitchen devices – all require electrical energy or electricity. Electricity is used to, and can be created, by solar energy, which is converted to direct current (DC), through the use of photovoltaic cells, then converted to electricity which can be used to charge batteries. This is the most common grid-tied electric system, without batteries, any excess electricity generated flows out. This flow can be caught by a collection system that then stores the extra energy.
However, with the rapid interest in renewable energies in the United States; there is a great future opportunity for the electrician renovator to develop and design, build, and maintain an energy efficient, low cost electrical system for people to use electric energy. It does not add to environmental problems as the regular use of fossil fuels has done. It offers the prospect of a new frontier in energy usage technology.
