Electricity is potentially dangerous and has inherent risks, especially as a result of circuit failure, misuse, inexperienced handling or negligence. <\/span>The effects on humans, devices and other objects can be devastating. <\/span>When installing an electrical circuit, extending an existing circuit, or looking for a new office or guest house, a full facility assessment is recommended. <\/span>Complete evaluations must ensure that the circuit can safely handle the required current flow, adequate protective devices are provided, the circuit is grounded, and there are no potential hazards.<\/span><\/span><\/strong><\/p>\n

For equipment, the risks of an incorrectly installed or secured circuit are short circuits and overloads. <\/span>For people, insulation faults create risks resulting in direct or indirect contact with electrical currents.<\/span><\/span><\/p>\n

A short circuit is a strong overcurrent that lasts for a short time. <\/span>In single-phase systems, a short circuit occurs when the phase and neutral wires accidentally touch; <\/span>In three-phase systems, this can happen when there is a connection between two phases. <\/span>For direct current, a short circuit may occur when the electrodes touch.<\/span><\/span><\/p>\n

A short circuit can also occur when there is a break in the insulation surrounding the cable, when two conductors come into contact via an external conductor (eg: a metal hand tool), or when water gets between line connections, causing the resistance of the circuit to approach zero and thus It reaches high values \u200b\u200b(U=RxI) very quickly.<\/span><\/span><\/p>\n

Physical damage may expose cables within the insulation, while a sudden increase in conductor temperature may cause the insulation and copper core to melt.<\/span><\/span><\/p>\n

Overload<\/span><\/span><\/span><\/strong><\/h3>\n

An overload is caused by a weak overcurrent that occurs over a long period of time. <\/span>Overloads may be caused by a current that is too high to be delivered through the relative diameter of the connecting cable.<\/span><\/span><\/p>\n

There are two types of overload:<\/span><\/span><\/p>\n
