A heiicai strand of resistance wire is encased in a sheath with magnesium oxide tigh^y packed belwee^^^
and
the sheath for electrical insulation Heal is generated in the resistance wire when 120 volts AC ts applied to it The
heal Is then transmitted through the magnesium oxide and through the sheath to the water or air surrounding it.
See Figure 9-3 for a cut-away view of the healer.
,,,,
The direct causes for the element to malfunction are,
1. Interruption of the electrical circuit to the heating eiement
2. The helical resistance wire becomes burned or broken
3. The helical resistance wire short-circuits to the sheath due to breakdown of the magnesium oxide
