Supporting electrical equipment

Foundations and structural steel supports for the electrical equipment (with Concrete and Structural Steel). 

Shut down all electrical equipment apart from life-support systems... 

The equipment floor is found between the hoist and deflection floors, and the floors end use is to support mechanical and electrical equipment associated with the hoisting plant During sinking the floor was used as a bulkhead to protect the personnel involved in sinking while hoist installation occmred. Additional steel and timber was placed on the floor in order to function as a bulkhead however, the majority of the elements were already installed. 

Same manufactured girder supports for electrical equipment. 

The caravan or motor caravan must be provided with a mains isolating switch and an RCD to break all live conductors (Regulations 721.411). An adjacent notice detailing how to connect and disconnect the supply safely must also be provided, as shown in Regulation 721.514. Electrical equipment must not be installed in fuel storage compartments (Regulation 721.528.3.5). Caravans flex when being towed, and therefore the installation must be wired in flexible or stranded conductors of at least 1.5 mm cross-section. The conductors must be supported on horizontal runs at least every 25 cm and the metalwork of the caravan and chassis must be bonded with 4.0 mm cable. 

Considering an outline design as suggested by Little (2011), the collected electrical energy from solar collectors in Satellite 1 at GEO would be beamed to Earth by lasers onto Satellite 2 positioned some 20 km above the Earth. Satellite 2 would support the equipment to transform the laser to microwaves, which would be beamed to a ground receiver. Ideally, the structural system to support the collectors and equipment for Satellites 1 and 2 would be fabricated from a polymer/fibre composite skeletal structure however, it is the structural support system for Satellite 1 at GEO which this chapter has discussed. The two satellites in relationship to the sun and Earth are shown in Rg. 10.11. 

The calculated stresses and reaction loads in the equipment and equipment supports should be a direct output of either dynamic or static analysis. It should be noted that electrical equipment, exclusive of anchorage or... 

These paragraphs apply to structures that support overhead electric power transmission and distribution lines and equipment. They do not apply to portions of buildings, such as loading docks, or to electric equipment, such as transformers and capacitors. Subpart M of this part contains the duty to provide fall protection associated with... 

Install abulkhead panel to provide mechanical support, electric grounding, and lightning protection for coaxial cables, power feeds, and telephone Hnes entering the equipment budding. 

Chapter 10 covers electrical installations in medical locations and associated areas. As in the case of Chapter 9, there are no equivalent regulations in the main standard and the guidance is based on lEC and CENELEC standards. The chapter considers the use of electrical equipment in three main areas life-support equipment (such as infusion pumps and dialysis machines), diagnostic equipment (such as X-ray machines and blood pressure monitors) and treatment (such as defribillators). It comments that the risks of electrical injury are enhanced by factors such as the acute nature of the care that patients may be undergoing and the fact that some treatments may be given when the skin barrier is broken, leading to reduced total body resistance. 

The mandatory standards include requirements specific to mines such as those pertaining to roof support, ventilation, permissible electrical equipment, ground control, hazardous dust control, and other standards that would be pertinent to any heavy industry. The mandatory standards also impose...
