3. Run conduit from the power distribution panel to the conduit hub on
the lower left side of the heated enclosure labeled for the heater
power input. Refer to “Application of Conduit Lubricant” on page
3-10.
4. Pull ground, neutral and hot wires (#14 AWG minimum) into the
power terminal box inside the heated enclosure.
Conduit seals should be used where appropriate in compliance
with local regulations.
Because the breaker in the power distribution panel or switch will
be the primary means of disconnecting the power from the
heater, the power distribution panel should be located in close
proximity to the equipment and within easy reach of the operator,
or within 10 feet of the analyzer.
An approved switch or circuit breaker rated for 15 amps should be
used and clearly marked as the disconnecting device for the
heater.
