Outlet receptacles

All 110-volt (V) outlet receptacles in laboratories should be of the standard design that accepts a three-... 

Molding Powders. Urea-formaldehyde resins are compounded with alpha-cellulose cotton fiber reinforcement to produce molding powders (4 percent) for compression, transfer, and injection molding. Typical molding conditions are 127 to 182°C and 2000 to 8000 psi. They are superior to phenolics in white color, electrical resistance, and low cost, but are limited by moisture sensitivity (Table 3.13). They are used primarily in electrical wiring devices such as wall outlets, receptacles, electric blanket controls, circuit breakers, and knob handles. Smaller amounts are used in bottle caps, housewares, buttons, and sanitary ware. 

Figure 3-94. This wire system for GE Plastics Living Environments Concept House seen in Chapter 1 is made of GE s Noryl resin, for high heat resistance and easy processing. The raceway is a wire channel that runs along the wall, much like a baseboard, to contain electrical outlets, receptacles, telephone plugs, and cable connections. This extruded resin prototype raceway, which is featured in every room, as a UL 94 flammability listing of V-O.

The control panel contains a vacuum gauge, an infinite range switch to control the heater temperature and an indicator light that shines when the heater is on. The switch on the right side of the panel activates an outlet receptacle mounted on the right front leg of the machine. If you were to use an electric vacuum pump it would plug into this outlet. The indicator light above the switch lets you know when the switch is on. 

Syringing liquid from a bottle or flask under inert atmosphere Before attempting to syringe liquid from a bottle which is under an inert atmosphere, make sure you have an effective inert gas system with a needle outlet a dry syringe (and preferably a spare) prepared as described above and a receptacle, also under inert conditions, into which you are going to transfer the liquid. The procedure outlined below should be practised with solvent first if you have not done it before. 

The comprehensive materials and work hours charts (Figs. 19.10 and 19.11) were developed from a theoretical model of a plant with one hundred 460 V motors of different sizes, half of them with interlocks, including allowance for lighting, welding receptacles, 110 V outlets, and grounding, directly proportional to the average hp/motor. The material costs and labor hours are based on the composite unit costs in Table 19.24.

The size of outlet piping required for a safety disc is not necessarily the same as the disc receptacle size. Discs frequently are sized on the basis of pressure requirements rather than capacity requirements. In such instances it is possible for the outlet piping to be smaller than the pipe size of the disc receptacle. If an arrangement of this type is desirable, the pipe diameter must be calculated on the basis of the relief capacity requirements and the maximum allowable upstream pressure. The inlet piping, however, must have an area which is at least equal to that of the receptacle in order to comply with the ASME code. 

Receptacle- An electrical outlet. A typical household will have many 120 volt receptacles for plugging in lams and appliances and 240 volt receptacles for the range, clothes dryer, air conditioners, etc. 

The National Hectrical Code (NEC) covers the safe and proper installation of wiring, electrical devices, and equipment in private and public biuldings. NEC is published by the National Fire Protection Association (NFPA) every three years. As an example of an NEC provision, the receptacle oudets in a room in a dwelling should be placed such that no point on the wall space is more than 6 ft away from the outlet in order to minimize the use of extension cords. After performing a Web search or obtainii a copy of the NEC handbook, give at least three other... 

Fig. 2. Multichannel assembly of toxicity test units, (a) Components included an electronic timer (A), liquid flowmeters (B), mixing chambers used for insoluble (C) and soluble (D) toxicants peristaltic pump (E), and exposure chambers (F). Syringe pumps were mounted outside the environmental room to avoid effects of low temperature and high humidity on operation, (b) View of magnetic stirrers (F) situated beneath the drainboard used to support exposure chambers (E). (c) A bank of 10 exposure chambers housed in a 6 ft x 10 ft environmental room. Inlet lines from mixing chambers (A) were attached with rapid disconnects (black arrow). The watertight drainboard (B) contained spillage. Test chamber outlet lines (white arrow) were connected to waste receptacles (C). (Copyright ASTM, 1916 Race Street, Philadelphia, PA 19103.

At construction sites, the most common electrical hazard is the grovmd fault electrical shock. The OSHA electrical rules reqrure employers to provide either (1) grormd fardt circuit interrupters (GFCIs) for receptacle outlets, or (2) an assraed equipment grormd-ing conductor program. Either method can eliminate grormd fault electric shock hazards. 

You are required to provide approved ground fault circuit interrupters for all 120-volt, single-phase, 15- and 20-ampere receptacle outlets on construction sites not a part of the permanent wiring of the structure and which are in use by employees. Receptacles on the ends of extension cords are not part of the permanent wiring and must be protected by GFCIs. 

The OSHA electrical standard requires your employer to provide either (1) GFCIs for receptacle outlets in use and not part of the permanent wiring of the structure or (2) an assured equipment grounding conductor program covering all cord sets, receptacles that are not part of the permanent wiring of the structiore, and equipment connected by cord and plug that are for use by employees.

Tanks installed inside buildings can be of simple welded construction (Fig. 8). An important requirement is that the tank should have an inclined or a hoppershaped bottom, so that moisture and impurities will settle at the lowest point and can be drained off there. For this reason, too, the tanks should be mounted sufficiently high above floor to allow a drum or other receptacle to be placed under the outlet. 

Make sure power receptacles are carefully marked. Many plants have both 115- and 220-V outlets. The computer has a slide switch on the back of the machine that allows it to be plugged into either a 115- or a 220-V receptacle. If the machine is set on 115-V and is... 

Certain aspects of fire prevention may be regulated by federal or state law, local codes, and institutional regulations. These factors include, but are not limited to, location of sprinkler systems, egress requirements, fire exit drills, placement and testing of fire extinguishers, etc. Some of these rules will have an effeet on the day-to-day laboratory operations, such as any regulations on the use of electrical extension cords, multiple receptacle boxes, or cube tap multiple outlet devices.
