Space building marine electrical equipment

Space building marine electrical equipment

In an electric power system , switchgear is composed of electrical disconnect switches, fuses or circuit breakers used to control, protect and isolate electrical equipment. Switchgear is used both to de-energize equipment to allow work to be done and to clear faults downstream. This type of equipment is directly linked to the reliability of the electricity supply. The earliest central power stations used simple open knife switches , mounted on insulating panels of marble or asbestos.

Ships Electrical Standards (2018) - TP 127 E

As stated in However, complying with NEC rules and regulations will not necessarily provide an installation that is efficient, convenient or adequate for good service or future expansion of electrical use. For example, an electrical service is needed for a small industrial occupancy. A load calculation for this occupancy was performed in accordance with Article , and the minimum size service was amperes A.

In accordance with Table While installing a A service would comply with the Code, there would be little room for future expansion of electrical use. The requirements in Section Subtopics in this section include working space, clear spaces, entrance to and egress from working spaces, illumination, dedicated equipment space and locked electrical rooms or enclosures.

Section This subsection is divided into indoor and outdoor installations. Indoor installations shall comply with The first subsection for indoor installations shows the required dedicated equipment space, which is sometimes referred to as the equipment footprint.

The second subsection under indoor dedicated equipment space pertains to foreign systems. The area above the dedicated space required by This does not mean it is OK for the area above the electrical equipment to contain foreign systems. The area mentioned in this subsection is the area above the dedicated equipment space. The dedicated space is 6 feet above the top of the equipment unless there is a structural ceiling; then the dedicated space is up to the structural ceiling.

If the structural ceiling is 6 feet or less above a switchboard, switchgear, panelboard or motor control center, no foreign system would be permitted in this zone. Foreign systems can be installed above the 6-foot zone, but if there is a possibility the electrical equipment could be damaged from condensation, leaks or breaks in such foreign systems, some type of protection has to be installed.

The protection can be fairly simple, such as wrapping an HVAC duct with insulation to avoid condensation. For piping containing liquids, a drip pan installed below the piping could protect the electrical equipment in the event of leaks or breaks.

For example, the distance from the top of a panelboard to the structural ceiling is 8 feet. A copper plumbing pipe has been installed above the panelboard and above the 6-foot dedicated equipment space. To protect the panelboard from possible leaks in the plumbing pipe, a drip pan has been installed above the panelboard under the pipe. Because the plumbing pipe and drip pan have been installed above the dedicated equipment space and leak protection has been installed, this installation is permitted see Figure 1.

A foreign system as mentioned in Raceways, junction boxes and troughs containing electrical conductors are not foreign to the electrical system and, therefore, can be installed within the dedicated equipment space. Items such as HVAC ducts, gas pipes, water pipes and drain pipes are foreign to the electrical system and, therefore, shall not be installed within the dedicated equipment space. Leak protection, such as a drip pan, shall not be installed within the dedicated equipment space either.

For example, the distance from the top of a panelboard to the structural ceiling is 7 feet. To protect the panelboard from possible leaks in the plumbing pipe, a drip pan has been installed under the pipe above the panelboard. Because the drip pan has been installed within the dedicated equipment space, this installation is not permitted see Figure 2. The third subsection under indoor dedicated equipment space pertains to sprinkler protection.

Like the requirements for foreign systems, sprinkler protection can be located above the 6-foot zone, but there has to be some type of protection from condensation, leaks or breaks.

This is not saying fire sprinkler heads cannot be installed to protect electrical equipment; sprinkler protection such as a fire sprinkler pipe can be located above the 6-foot zone, but there has to be some type of protection from condensation, leaks or breaks. A fire sprinkler pipe has been installed above the panelboard and above the 6-foot dedicated equipment space. To protect the panelboard from possible leaks in the pipe, a drip pan has been installed under the pipe above the panelboard.

Because the sprinkler pipe and drip pan have been installed above the dedicated equipment space and leak protection has been installed, this installation is permitted see Figure 3.

The fourth subsection under indoor dedicated equipment space pertains to suspended ceilings. Having a suspended ceiling located above a panelboard and within the 6-foot zone does not mean systems foreign to the electrical installation can be installed above the suspended ceiling.

A suspended ceiling is not considered a structural ceiling. In accordance with the exception to For example, a panelboard has been mounted on a concrete block wall. The structural ceiling is 6 feet above the top of the panelboard.

A suspended ceiling is 2 feet above the panelboard. The suspended ceilings can be installed within the 6-foot zone because it has removable panels see Figure 4.

K Higher Education. Distribution Centers Manufacturing Storage Facilities. Data Centers Telecommunication. A panelboard also sometimes referred to as a load center is an enclosure which contains overcurrent devices such as fuses or circuit breakers. In a commercial building it is typical for space to be dedicated for electrical panels and equipment.

We are located at the Beatrixhaven. We provide service, repairs and parts, as well as inspections, to technical installations and equipment on board ships such as, but not limited to:. If needed we can lift up to T from the water in Eemshaven in case of underwater repairs.

Marine engineers and naval architects design, build, and maintain ships, from aircraft carriers to submarines and from sailboats to tankers. Marine engineers and naval architects typically work in offices, where they have access to computer software and other tools necessary for analyzing projects and designing solutions. Sometimes, they must go to sea to test or maintain the ships that they have designed or built. The need to design environmentally friendly ships and systems to transport energy products, such as liquefied natural gas, across the globe will help to spur employment growth for this occupation.

Where can panelboards and load centers be located in my building?

A worker must be informed of the potential electrical hazards before being permitted to do work in proximity to energized electrical conductors or equipment. Note : If excavating near underground utilities, refer to the excavation requirements in Part 20 Construction, Excavation and Demolition. If practicable, service rooms and electrical vaults must be used only for the purpose for which they were intended. Each electrical distribution switch, circuit breaker and control must be clearly marked to indicate the equipment it serves.

Cultural property management is entrusted with the responsibility of protecting and preserving an institution's buildings, collections, operations and occupants. Constant attention is required to minimize adverse impact due to climate, pollution, theft, vandalism, insects, mold and fire. Because of the speed and totality of the destructive forces of fire, it constitutes one of the more serious threats. Vandalized or environmentally damaged structures can be repaired and stolen objects recovered. Items destroyed by fire, however, are gone forever. An uncontrolled fire can obliterate an entire room's contents within a few minutes and completely burn out a building in a couple hours. The first step toward halting a fire is to properly identify the incident, raise the occupant alarm, and then notify emergency response professionals.

An electrical room is a room or space in a building dedicated to electrical equipment. Its size is usually proportional to the size of the building; large buildings may have a main electrical room and subsidiary electrical rooms. Electrical equipment may be for power distribution equipment, or for communications equipment. In large building complexes, the primary electrical room may house an indoor electrical substation.
