Sample regulations for safe dealing with electrical equipment

GENERAL RULES FOR ELECTRICAL SAFETY

  • Use electrical cords only if they are in good condition. Cords must not be cracked, frayed, or have corroded prongs.
  • Do not use 3-to-2 prong adapters unless other grounding provisions have been made. Plug 3-prong plugs into 3-prong outlets.
  • Use power strips that have circuit breakers or fuses. Do not link power strips in series. 
  • Do not leave cables and cords unsecured and hanging in areas where they can pose a trip and movement hazard. Place cords so that they are not subjected to mechanical stress or temperatures that could damage the insulation.
  • Do not conceal cords behind or attach electrical cords to building surfaces.
  • Do not leave electrical circuits exposed. Use electrical tape to insulate wires or use a guard as cover to prevent accidental contact.
  • Do not block access to electrical panels.
  • Do not install standard electrical equipment in locations where flammable gases, vapors, dusts, or other easily ignitable materials are present. If electrical equipment is used in a chemical fume hood, elevate it to allow efficient air flow.
  • Keep electrical equipment at a minimum in high-moisture areas (e.g., wash rooms, cold rooms).

Hydro-electricity and power transmission

A precious read on the history of electrical sciences on the basis of Canadian Quebec.
Highly recommended:

Intro to Robotics

Here's some short presentation introducing the reading into the basic concepts of robotcs engineering.

And here is a link to a very interesting article containing some intro on Robotics as well as some overview of challenges resulting from the progress of robotics engineering.

And, finally, enjoy the NASA page which includes Mars rover stories (which is also some kind of robot, isn't it?)
