On the other hand, an earth fault is a phenomenon in which electric current escapes to a location where it should not normally flow.<\/p>\n<p>Broadly speaking, a short circuit is a type of overcurrent, but it is characterized by electric currents that are orders of magnitude greater than those caused by normal overloads.<\/p>\n<p>During a short circuit, depending on the equipment conditions, extremely high electric currents\u2014ranging from hundreds to thousands of times the normal operating current\u2014can flow, instantly damaging wiring and equipment. In contrast, overcurrent caused by an overload refers to a state where an electric current several times the rated value flows continuously.<\/p>\n<p>&nbsp;<\/p>\n<h3 style=\"color: #fff; background: #c3effa; line-height: 20px; font-size: 23px; margin: 10; padding-left: 1em; padding: 1em;\"><span style=\"color: #000000; font-size: 18pt;\">Types of Overcurrent for Electric Currents<\/span><\/h3>\n<p>There are two types of overcurrent: overcurrent caused by short circuits and overcurrent caused by overloads.<\/p>\n<p>Let\u2019s understand the characteristics of each so that we can select the appropriate countermeasures.<\/p>\n<div style=\"overflow-x: auto;\">\n<table style=\"width: 100%; max-width: 100%; border-collapse: collapse;\">\n<tbody>\n<tr style=\"height: 23px;\">\n<td style=\"width: 18.1355%; background-color: #f0fff8; padding-top: 2px; padding-bottom: 4px; border: 1px solid #999999; height: 23px;\">Types<\/td>\n<td style=\"width: 27%; background-color: #f0fff8; padding-top: 2px; padding-bottom: 4px; border: 1px solid #999999; height: 23px;\">Mechanism of Occurrence<\/td>\n<td style=\"width: 27%; background-color: #f0fff8; padding-top: 2px; padding-bottom: 4px; border: 1px solid #999999; height: 23px;\">Characteristics of Electric Current<\/td>\n<\/tr>\n<tr style=\"height: 14.4133px;\">\n<td style=\"width: 18.1355%; background-color: #ffffff; padding-top: 2px; padding-bottom: 4px; border: 1px solid #999999; height: 14.4133px;\">Overelectric Current Caused by a Short Circuit<\/td>\n<td style=\"width: 27%; background-color: #ffffff; padding-top: 2px; padding-bottom: 4px; border: 1px solid #999999; height: 14.4133px;\">Caused by wiring errors or equipment failure<\/td>\n<td style=\"width: 27%; background-color: #ffffff; padding-top: 2px; padding-bottom: 4px; border: 1px solid #999999; height: 14.4133px;\">An extremely large electric current flows instantaneously<\/td>\n<\/tr>\n<tr style=\"height: 23px;\">\n<td style=\"width: 18.1355%; background-color: #ffffff; padding-top: 2px; padding-bottom: 4px; border: 1px solid #999999; height: 23px;\">\u00a0Overcurrent Due to Overload<\/td>\n<td style=\"width: 27%; background-color: #ffffff; padding-top: 2px; padding-bottom: 4px; border: 1px solid #999999; height: 23px;\">Using too many electrical devices at once, or excessive load on a motor<\/td>\n<td style=\"width: 27%; background-color: #ffffff; padding-top: 2px; padding-bottom: 4px; border: 1px solid #999999; height: 23px;\">An electric current exceeding the rated value flows continuously<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<p>A short circuit occurs due to wiring errors or equipment failure, causing a massive electric current to flow instantly.

Internal short circuits caused by equipment failure can also lead to overelectric current.<\/p>\n<p>This occurs, for example, when the insulation of the coils inside a motor deteriorates, causing the windings to come into contact with each other. Additionally, lightning surges caused by lightning strikes generate a large instantaneous electric current, causing the circuit breaker to trip and cut off the electric current.<\/p>\n<p>&nbsp;<\/p>\n<h3 style=\"color: #fff; background: #c3effa; line-height: 20px; font-size: 23px; margin: 10; padding-left: 1em; padding: 1em;\"><span style=\"color: #000000; font-size: 18pt;\">Due to an overload on electrical equipment<\/span><\/h3>\n<p>Using too many electrical devices at once overloads the circuit, causing electric current to flow beyond the rated capacity.<\/p>\n<p>For example, if multiple high-power devices are connected to the same circuit and operated simultaneously, the electric current will continuously exceed the wiring\u2019s rated capacity.<\/p>\n<p>Similarly, placing a heavy load on a motor results in an electric current exceeding the rated value.<\/p>\n<p>When an industrial motor lifts heavy objects or a compressor starts under high pressure, the electric current flowing can be 4 to 8 times that of normal operation, and in some cases, more than 10 times during the initial cycle. If this condition persists for a long time, it can lead to overheating of the wiring and damage to the equipment.<\/p>\n<p>&nbsp;<\/p>\n<h3 style=\"color: #fff; background: #c3effa; line-height: 20px; font-size: 23px; margin: 10; padding-left: 1em; padding: 1em;\"><span style=\"color: #000000; font-size: 18pt;\">Due to the deterioration of wiring and circuits<\/span><\/h3>\n<p>In older buildings, the insulation on wiring tends to deteriorate, making insulation failures more likely.<\/p>\n<p>As insulation hardens and cracks due to aging, it can lead to exposed conductors, contact between conductors (short circuits), and ground faults (leakage electric current), which is dangerous. Continuing to use the equipment in this condition can cause the circuit impedance to drop, allowing high electric currents to flow and potentially resulting in overcurrent.
