Each 480-volt, three-phase, wye-connected feeder disconnect with a minimum rating of 100 amperes is required to be ground-fault protected.
A feeder disconnect is the main electrical disconnecting device in an electrical circuit. It provides an accessible location for disconnecting all conductors at one time and is usually located near the source of power. Feeders can consist of cables or busbars.
To be considered a feeder, it must have a voltage that exceeds 50 volts under normal conditions and must supply more than one receptacle or piece of equipment. A feeder disconnect must have a minimum rating of 100 amperes or less and may be rated up to 1000 amperes or higher depending on how much power it supplies to its load(s).

<u>Answer:</u>
<em>The chemical reactions involves changes in energy due to the changes in the breaking and building of bonds.</em>
<u>Explanation:</u>
The changes in energy that chemical reactions involves are:
- <em>Endothermic(absorbing) chemical reactions.</em>
- <em>Exothermic(releasing) chemical reactions. </em>
Endothermic: The chemical reactions which absorbs the energy those chemical reactions are called endothermic chemical reactions.
Exothermic: The chemical reactions which releases the energy those chemical reactions are called exothermic chemical reactions.
The similarity in the reactions is both reactions are related to the change in energy. In one reaction the energy is absorbing and in another reaction the energy is releasing.
