Resumo(s)
In electrical installations and equipment, electric current preferentially flows through metallic circuits that offer it less opposition,
that is, less electrical resistance. In the human body, electric current also seeks to flow through paths with less electrical
resistance, and may be diverted inside the body, damaging surrounding organs and tissues. Its path and the magnitude of the
current influence the type of injuries associated with electrical accidents, usually burns, which can be internal and external. In
all electrical installations, there is a need and obligation to implement effective protection systems, with the aim of operating
them under safe conditions. In Low Voltage Electrical Installations (LVEI), the protection measures that must be considered are
overcurrent protection, overvoltage protection, but fundamentally the protection of people from the risk of electrocution, avoiding
pathophysiological effects that can be irreversible.
