Final answer:
Tamper-resistant receptacles are not generally required for dedicated and stationary appliances. Modern three-wire systems with three-hole outlets include a ground wire that enhances safety by enabling the circuit breaker to trip in case of insulation wear or fault.
Step-by-step explanation:
The situation described, where a single receptacle for one appliance or a duplex receptacle for two appliances is within a dedicated space for each appliance, and these appliances in normal use are not easily moved from one place to another and are cord-and-plug connected, generally does not require tamper-resistant receptacles.
Tamper-resistant receptacles are typically mandated in areas accessible to children, such as residences, schools, childcare facilities, and similar locations. However, certain local electrical codes or regulations may specify specific instances or locations where tamper-resistant receptacles are necessary for safety reasons, regardless of the appliance type or its permanence in a space.
In the described scenario where appliances are situated within dedicated spaces and are not easily moved, the requirement for tamper-resistant receptacles may not apply, as these receptacles are primarily intended to prevent accidental electric shock or injury in areas where children might be present and have access to electrical outlets. Always consult local electrical codes or regulations for precise requirements in specific situations.
