In electrical power distribution, the US National Electrical Code (NEC), NFPA 70, article 725 (2005), defines low distribution system voltage (LDSV) as up to 49 V. The NFPA standard 79 article 6.4.1.1 defines distribution protected extra-low voltage (PELV) as nominal voltage of 30 Vrms or 60 V DC ripple-free for dry locations, and 6 Vrms or 15 V DC in all other cases.Low Voltage (LV) - 240 to 600 VAC.

Other requirements such as: Zone Selective Interlocking of breakers, 100% rated breakers, drawout or electrically operated breakers and key interlock schemes can be overlooked if they are not documented on a Single .
The electric circuit safeguarding fault currents against Thermo – mechanical shocks is a crucial role of LV switchgear. It is critical to reducing the dangers of high currents and isolating the faulty current from the remainder of the system. Human operators and devices like electrical machines are protected by LV switchgear. In addition LV switchrooms often also house other related equipment – marshalling panels, UPS systems, control panels etc.. This article gives some design guidance for the correct sizing of these rooms. Switchboards. In laying out the LV switchroom, actual switchboard dimensions should be used. Typical switchboard dimensions would be: The Electrical Installation Guide is now available here as a wiki (Electrical Installation Wiki). This wiki is a collaborative platform, brought to you by Schneider Electric: our experts are continuously improving its content, as they were doing for the guide. Collaboration to this wiki is also open to all.HV (high voltage) and LV (low voltage) are the two basic categories (low voltage). HV type is used to power motors and electrical equipment that operate on more than 1000 volts AC, whereas LV type is used to power electrical devices running on less than 1,000 volts AC.

These studies assure that circuit breakers are capable of interrupting the available current and would operate “selectively”. Traditionally, “selectivity” in a low voltage electrical system meant that the long time and short time portions of time-current curves (TCCs) would be selective, i.e. the circuit breaker closest to the fault would trip first, maximizing the amount of .
