Nikola Tesla was an inventor and futurist who is best known
for his contributions to the design of the modern alternating current (AC)
electricity supply system.
Smart Homes of the future using the Internet of Things will
require specialized electrical needs. IoT devices can include lighting, heating
and air conditioning, media and security systems, and wiring for data.
The National Electrical Code establishes requirements for electrical wiring and equipment. Electrical codes provide standards to ensure electrical wiring systems are safe.
Wire gauge is a measurement of wire diameter. This
determines the amount of electric current a wire can safely carry, as well as
its electrical resistance and weight.
Electricity is a flow of electrons. A complete circuit is
needed for electricity to flow. From the main electric service panel,
electricity is divided into circuits throughout a building.
The three basic units of electricity are voltage, current
and resistance. Voltage is measured in volts, current is measured in amps and
resistance is measured in ohms.
A circuit breaker’s job is to limit the amount of current
flowing on a circuit so that it doesn’t exceed the rated level. The most common
cause of circuit breaker failure is continually overloading it, causing it to
trip out or open the circuit.
Surge protectors are devised to protect electronic devices
from voltage spikes. Surge protectors limit the voltage supplied to an electric
device if a voltage spike occurs.
Improvements and repairs involving electricity should only
be performed by licensed professionals. Professional contractors are
experienced and knowledgeable, with state approved licenses.
