46.2.2 The heat source illustrated in Figure 46.1 is to be
constructed of sheet metal having an average
thickness of 0.81 mm (0.032 inch). The thermal
insulation is to weigh 16.02 kilograms per cubic
meter (1 pound per cubic feet). The heat source is
to be approximately 381 mm (15 inches) deep,
front to back, including the 25.4-mm (1-inch) thick
door. The door is to be hinged on the left side and
may be closed or opened as much as 101.60 mm
(4 inches). The elements are to consist of coiled
resistance wire embedded in fused magnesium
oxide completely enclosed in nickel-alloy stainless
steel. The heat from the source is to be controlled
with a thermostat in which the bulb and capillary
tube are located at the top of the heat source,
toward the side.

46.3 Controllers N/A
46.3.1 For the temperature test, a separate controller –
that is, a controller that is not a physical part of the
appliance – that is intended for installation in a wall
is to be mounted as follows. The controller is to be
secured inside its own enclosure, if provided.
Otherwise, it is to be installed inside the smallest
standard flush-type outlet box that accommodates
it, and the box is to be mounted in a simulated wall
section as illustrated in Figure 46.2.
N/A
47 Dielectric Voltage Withstand Test P
47.1 An appliance shall withstand for 1 minute without
electrical breakdown the application of a DC
potential or an AC potential at a frequency within
the range of 40 to 70 Hz between the following:
P
a)Uninsulated live metal parts and the enclosure. A
non-conductive enclosure is to be wrapped in
conductive foil.
P
b)Terminals of opposite polarity. P
47.3 Capacitors connected across-the-line or line-to-
ground shall withstand a DC dielectric potential of
1414 volts plus 2.828 times the maximum rated
supply voltage, without breakdown for 1 minute,
between the terminals of the capacitor, and
between the terminals and foil wrapped around the
case of the capacitor. The test shall be conducted
with the capacitor at normal operating temperature.
