Electrical Room Space Requirements
Consultant’s Corner: Electrical Room Space Requirements Electrical room space requirements The space requirements for standby and emergency power systems do not rank at the top of an architect's design list. Consequently, service personnel can find themselves in tight quarters when these power systems are jammed into areas that meet only minimum safety requirements and don't take serviceability into account. Building service equipment must have an advocate early in the design process. It is far easier and less expensive to plan for adequate space in the design phase than to compromise on unit size and retrofit equipment to fit in cramped areas. Basic room requirements Minimum requirements set for the National Fire Protection Association (NFPA) in the National Electric Code (NEC) is that a person must be able to complete service duties with enclosure doors open and for two people to pass one another. If maintenance must be done at the rear of the cabinet, similar access space must be available. The NEC also requires 3 to 4 feet (1m to 1.3m) of aisle space between live electrical components of 600 volts or less, depending on whether live components are on one or both sides of the aisle. This requirement hold even if components are protected by safety enclosures or screens. Installations over 600 volts require even wider aisle space, from 3 feet (1m) to as much as 12 feet (4m) for voltages above 75kV. Service rooms with 1,200 amps or more require two exits in case of fire or arcing. Because transformers vary, make sure minimum wall clearances are met as specified by the manufacturer. -

For further information contact the UOW Library: [email protected] A review of protection systems for distribution networks embedded with renewable generation Abstract The rapid growth of grid-connected embedded generation is changing the operational characteristics of power distribution networks. Amongst a range of issues being reported in the research, the effect of these changes on so-called 'traditional protection systems' has not gone without attention. Looking to the future, the possibility of microgrid systems and deliberate islanding of sections of the network will require highly flexible distribution management systems and a e-designr of protection strategies. This paper explores the envisaged protection issues concerned with large penetrations of embedded generation in distribution networks extending into auto-reclosure and protection device coordination. -

(This includes whether or not the windings are referenced to earth.) • The system configuration is not based on how any specific load or equipment is connected to a particular power distribution system. 1. Definitions Ground Fault Protection System •A designed, coordinated, functional, and properly installed system that provides protection from electrical faults or short circuit conditions that result from any unintentional, electrically conducting connection between an ungrounded conductor of an electrical circuit and the normally non–current-carrying conductors, metallic enclosures, metallic raceways, metallic equipment, or earth. 1. Definitions Ground Fault Protection of Equipment (Per Article 100 in the 2005 NEC) • “A system intended to provide protection of equipment from damaging line-to-ground fault currents by operating to cause a disconnecting means to open all ungrounded conductors of the faulted circuit. -

Electrical Redesign for Greenwich Academy Upper School
| Greenwich Academy Upper School Matthew Fracassini | | Senior Thesis 2004 PSU AE | Electrical Redesign for Greenwich Academy Upper School general description: Power is supplied to the Upper School by an existing 13.2 kV connection located on the exterior of the adjacent building, Ruth West Campbell Hall. A new 750 kVA transformer was added during construction to step the voltage down 208Y/120 V. The transformer is located in a vault beneath the exterior stairway closest to the Gym Building. A 4” conduit bank consisting of three (3) #2 (15kV rated) cables feeds the 3000 A Main Distribution Panel (MDP) located in the basement. This switchboard provides 3-phase power to all of the panels in the building. emergency power: A 200 kW Generator, located in the same vault as the transformer, provides 3- phase power at 208/120 Volts. The generator is connected by 2 sets of 4 500MCM THHN conductors to an 800 A Automatic Transfer Switch in order to ensure safe shifting of the loads in the event of a power fault. The emergency switchboard supplies the emergency lighting system and emergency receptacles, as well as the hydraulic elevator with 208/120 V power. overcurrent devices: The overcurrent protection devices are all located on the Main Distribution Panel (MDP) or the emergency distribution panel (MDP-EM) in the Electrical Room. At this switchboard, all of the panels are protected from overload and ground faults by 3-pole circuit breakers of various capacities. Fused disconnect switches are used to protect from high-level short-circuits. The panels themselves are protected by a 3000 A 3-pole breaker and a 2500A fused disconnect switch. -
