Study Notes

Electrical Outlets

2-prong electrical outlets are being phased out due to safety concerns.
3-prong electrical outlets prevent electrical shock by providing a grounding path that directs electricity to the ground, reducing the risk of shock.

20-Amp Electrical Outlets

A 20-amp electrical outlet (125 V) differs from a standard 3-prong outlet in its higher current rating, indicating it can handle more power.
The recommended purpose of a 20-amp electrical outlet (125 V) is for heavy-duty appliances that require more power, such as refrigerators or air conditioners.

20-Amp Electrical Outlets (250 V)

The appearance of a 20-amp electrical outlet (250 V) differs from the 125-volt version, indicating it can handle a much higher voltage output.
20-amp electrical outlets (250 V) are suitable for appliances that require a higher voltage output, such as electric dryers or ovens.

Safety and Standards

2-prong electrical outlets are not considered safe due to the lack of grounding, which increases the risk of electrical shock.
3-prong electrical outlets are the standard for businesses and homes due to their enhanced safety features.
