Electrical panels

Storage areas for maintenance, janitorial, and other service organizations must be provided. Safety items such as fire extinguishers, firehose cabinets, safety hoops on permanent ladders, guard rads, shielding for acid pumps, clearance for electric panel boards, etc, are needed. Manholes and cleanouts for sewer pipes within the facility as well as in the landscape and parking areas should be provided.

Electric Tracing An electric tracing system (see Fig. 10-178) consists of an electric heater placed against the pipe under the thermal insulation, the supply of electricity to the tracer, and any control or monitoring system that may be used (optional). The supply of electricity to the tracer usually consists of an electrical panel and electrical conduit or cable trays. Depending on the size or the tracing system and the capacity of the existing electrical system, an additional transformer may be required. 

In solar NEVs the solar-electric panels and the charge controller keep the batteries charged while not overcharging them. The owner can park the NEV in the sun and the vehicle will charge itself. If it is a cloudy day and the owner wants to charge the vehicle, it can be plugged into ordinary house current. 

The Sunmobile SunVee is a solar neighborhood vehicle. Solar electric panels are integrated with the body to charge batteries which power an electric motor. The neighborhood range is about 30 miles with a top speed of about 25 miles/hour. The Sunmobile is based on a commercial four-wheeled, two person, pedaling bike, called a Rhoades Car. 

Poor housekeeping may also be a symptom of other fundamental problems, such as careless operation, frequent temporary repairs, and generally inadequate maintenance. These conditions can result in process leaks, releases, and spills, missing or open covers on equipment and electrical panels, unpainted rusting metal, and nonfunctional gauges and instruments.

Wiring problems were found in the electrical panel supplying the computers, such as with the neutral wires in the ground terminal and ground wires in the neutral terminal. This configuration caused a portion of the neutral return current of the load... 

From this device, several sub-versions were made. These so-called electrical panel devices were realized as three- and six-phase array devices and a nine (3x3) electrode dot device [100,101]. The three- and six-phase array devices consist of a substrate with electrode arrays of a paste printed on using a silkscreen printmaking process. This substrate is covered with an insulating covering film.

Agricultural buildings that house livestock require special care in selecting wiring materials, wiring methods because of the corrosive dust, gases, and moisture. Corrosion of metallic conduit, boxes, and fixtures lead to electrical system failure. Accelerated corrosion because of condensation occurs on electrical panels that are not properly designed.

Maintenance to most occupants of the buildings involves work either in their immediate area or directly affecting their area. An exception is the electrical panel which controls the breakers to electrical circuits within a laboratory. As noted earlier, there are reasons why employees other than maintenance personnel will need (sometimes urgently) to deactivate electrical circuits, and if proper isolation of the panels is done to prevent access to active electrical wiring, the breaker panel closets can be made safely accessible.
