10 Questions
Question 1 of 10
The NEMA 15-60R is configured as a 3-pole, 4-wire device. Which of the following correctly describes the conductor requirements for this receptacle?
The NEMA 15-60 configuration is explicitly designed for 3-phase loads that do not require a neutral connection, utilizing only three hot lines and a ground wire.
Question 2 of 10
When installing a NEMA 15-60 receptacle, what is the minimum recommended copper conductor size for the hot (phase) wires according to the provided specifications?
The article specifies #4-#6 AWG copper as the required wire size for the hot conductors for a 60A circuit.
Question 3 of 10
In accordance with terminal identification for the NEMA 15-60, which terminal corresponds to the 'Y' designation?
The article identifies the Y terminal as the vertical slot (I) connected to Hot 1 (Line 1).
Question 4 of 10
What is the recommended torque value for the terminal screws on a NEMA 15-60 receptacle installation?
The instructions explicitly state to tighten the terminal screws up to 25 in.-lb (3 N·m) or according to manufacturer specifications.
Question 5 of 10
If an outdoor installation of a NEMA 15-60 is required, which enclosure rating is mandated by the guidelines?
The article specifies using a NEMA 3R rainproof/weatherproof enclosure for outdoor installations.
Question 6 of 10
Which of the following describes the potential hazard when working inside a panel to install a 3-pole breaker for this receptacle?
The article warns that panel lugs above the main breaker remain energized even when the main breaker is in the OFF position.
Question 7 of 10
What is the primary reason the NEMA 15-60 configuration lacks a neutral terminal?
The NEMA 15-60 is a 3-pole, 4-wire device specifically designed for 3-phase loads that do not require a neutral connection.
Question 8 of 10
What is the approximate voltage and current rating of the NEMA 15-60 receptacle?
The receptacle is explicitly rated for 60A and 250V three-phase AC supply.
Question 9 of 10
Regarding the grounding conductor for a NEMA 15-60 installation, what is the minimum gauge size specified for the ground wire?
The wiring instructions indicate to pull (1) #10 AWG ground wire for the NEMA 15-60 receptacle.
Question 10 of 10
Which standard organization governs the terminal configuration (G, X, Y, Z) mentioned for the 15-60 receptacle?
The article states there are four terminals in a 15-60 receptacle in accordance with UL 498 and CSA standards.
