                                 CODE OF VIRGINIA

UNLAWFUL TO SELL OTHER CONTROLLING DEVICES UNLESS THEY MEET CERTAIN STANDARDS
(§ 55.1-2802)

A. A controlling device that does not conform to the requirements of §
55.1-2801 shall not be sold, distributed, constructed, installed, maintained, or
used unless it meets the following standards:

   1. A peak-discharge-output type controlling device that delivers intermittent
   current of a value not in excess of four milliampere-seconds for a maximum
   &#8220;on&#8221; period of two-tenths second and a minimum &#8220;off&#8221;
   period of three-quarters second. The mean value of the peak output from such
   device shall progressively decrease from four milliampere-seconds at maximum
   &#8220;on&#8221; periods of both two-tenths and one-tenth second to three and
   two-tenths milliampere-seconds at six-hundredths second, one and nine-tenths
   milliampere-seconds at three-hundredths second, and consequently to shorter
   &#8220;on&#8221; periods as output current increases.

   2. A sinusoidal-output type controlling device that delivers an intermittent
   current of a value not in excess of five milliamperes for a maximum
   &#8220;on&#8221; period of two-tenths second and a minimum &#8220;off&#8221;
   period of nine-tenths second. The effective value of the output from such
   device may increase as the &#8220;on&#8221; period decreases, increasing from
   40 milliamperes for one-tenth second to 57 milliamperes for five-hundredths
   second, and 65 milliamperes for twenty-seven thousandths second.

   3. Any other type of controlling device that delivers a maximum intermittent
   current output of a value not in excess of four milliampere-seconds for a
   maximum &#8220;on&#8221; period of two-tenths second and a minimum
   &#8220;off&#8221; period of nine-tenths second.

B. Notwithstanding the provisions of subsection A, no electric fence controlling
device shall be sold, distributed, constructed, installed, maintained, or used
that will permit for longer than one second an uninterrupted electric current on
the fence with an effective value in excess of five milliamperes when the load,
including the measuring device, is not less than 450 ohms nor more than 550
ohms.
