Power Distribution Clause Samples

Power Distribution. In switchboards, distribution panelboards, branch circuit panelboards and feeders and busways allow for: i. HVAC, plumbing, fire protection, elevator and lighting loads. ii. Minimum 25% spare capacity (over the fully built out building), in feeders, including breaker spaces in panelboards. iii. In electrical riser room on each floor provide sleeves in floor for future systems; include routing space from switchboard room to lowest typical floor electrical room.

Power Distribution a. Distribution shall be one electrical room for approximately each 19,000 usable square feet. b. A complete shell electrical system is provided in accordance with applicable codes from a 2000 amp, 277/480 volt, 3-phase service to panel boards with circuit breakers and distribution as required to provide power for HVAC equipment, lighting, and convenience outlets. c. Electrical rooms will provide two 120/208 volt panel boards with 75 KVA transformer. Each panel board shall have a 225 amp main breaker and provisions for 42 one pole bolt-on breakers. d. The electrical system and equipment will have a grounding system required by code.

Power Distribution. The data centers each contain redundant switchgear, PDU, and transformers rated at N+N. Cooling Equipment The data centers’ cooling systems retain a rating of N+N. Fire Suppression Fine detection systems constantly monitor both data centers. In case of fire, two detectors must trigger to activate the fire detection system. Only then does the system fill the sprinkler piping and spray out water from the activated sprinkler head in the data center. SS&C associates monitor fire protection systems.

Power Distribution. The building will be supplied by one 277/480 volts service from a Pepco pad mounted transformers. 2 separate utility transformers will be provided with a ▇▇ ▇▇▇ ▇▇▇▇▇▇▇▇ from each to 2 separate service entrance switchboards. The building switchboard will consist of the following:

Power Distribution. Main panel gear to be located at electrical/phone room area in warehouse.

Power Distribution unit The power distribution unit of the on-site control system and the power generating system shall be installed in a common panel. Low voltage (<50V) circuit shall be separated from the motor circuit. The distribution panel installed on the ground shall have a base stand, the minimum height of which is 100mm. The panel shall have a few cable seals to allow the ins and outs of all cables. Current-carrying components shall exceed the allowable temperature rise under restricted circumstance and able to continuously withstand the rated current under rated voltage. The distribution panel shall be equipped with multiplex coppery earth bus (PE). The bus shall be connected to cables and/or guard sheet of the ground conductor. The earth bus (PE) shall also be connected to the ground system. All components inside the distribution panel must be installed onto the installation board, whose surface is equipped with an intensive cover/door. All distribution panels (including their modules) shall meet the IEC requirements which set forth a minimum space and creep distance to the insulators. The bus shall be pure electrolytic copper. The wiring board shall be installed onto a standard installation board. All interior wiring shall be flexible single conductor cable with a minimum fracture surface of 1m m2. Every distribution panel shall be equipped with 15% spare wiring boards which are used for controlling the cut-in of wires. Every component inside the distribution panel shall be labeled according to the corresponding drawings. Phase flag shall be marked at the terminal of the power line. The controlling line shall be marked according to the wiring diagram provided by the Seller. The interior wiring must be ferruled and labeled according to the wiring diagram. All devices installed on the face plate shall be marked by planar and functional symbols. Safety symbols shall be in Chinese and English, other symbols and descriptive words can be in English.

Power Distribution. A complete electrical system shall be provided in accordance with applicable codes from a 120/208V, 3-phase 3600-amp service to panelboards with circuit breakers and distribution as required to provide power for building systems, lighting, and convenience outlets.

Power Distribution. Plants that require distribution of incoming power supply shall be equipped with distribution cubicles. Distribution shall take place by means of mechanical circuit breakers and/or miniature circuit breakers. In the smaller systems, distribution may be done directly in electrical and equipment cubicles. The short-circuit data of the supply network shall be taken into account when selecting and sizing components and cables. Efforts shall be made to achieve selectivity in order to limit the amount of isolated equipment in the event of a fault. In project design, efforts shall be made to achieve sectionalizing of the switching equipment in separate cubicles, compartments or modules. The aim is to limit the effect and spread of damage to electrical equipment and injury to personnel in the event of a fault in the electrical plant, such as arcing, etc. If sectionalizing and other sizing have been correctly carried out, some redundancy will thereby be obtained, which will allow for limited continued production. To allow for future expansion and additions, space shall be provided for additional groups of at least 25% of each type employed. Whether or not these shall be fitted with components will be decided on each procurement occasion. However, at least two spare groups of each type shall always be fitted with components and shall thus be included in the delivery. Terminals connected to the network shall always be preceded by current-sensing earth fault switches with a maximum rated tripping current of 30 mA.

Power Distribution. The power grid used for the equipment in 208VAC is comprised by circuits segmented by sectorial boards that supply power to the power strips of each rack or equipment. Each circuit is individually protected by a switch and short-circuit finder.
