The Commandments of the EE:

5:	Take care that thou useth the proper method when thou takest the
	measures of high-voltage circuits too, that thou dost not incinerate
	both thee and thy test meter, for verily, though thou has no company
	property number and can be easily surveyed, the test meter has
	one and, as a consequence, bringeth much woe unto a purchasing agent.
6:	Take care that thou tamperest not with interlocks and safety devices,
	for this incurreth the wrath of the chief electrician and bring
	the fury of the engineers on his head.
7:	Work thou not on energized equipment for if thou doest so, thy
	friends will surely be buying beers for thy widow and consoling
	her in certain ways not generally acceptable to thee.
8:	Verily, verily I say unto thee, never service equipment alone,
	for electrical cooking is a slow process and thou might sizzle in
	thy own fat upon a hot circuit for hours on end before thy maker
	sees fit to end thy misery and drag thee into his fold.
