Practice Code Look Up Two Minute Drill #7 Copyright 2005 Ted "Smitty" Smith Two Minute Drill #7

Directions Left click on the presentation ICON located at the bottom of the slide directory to the left of the this slide. Each slide will transition to the correct answer automatically in 2:30 minutes or less. The correct answer will transition in 10 seconds. Do not worry about writing down the correct answer for now. You will have the opportunity to do that at the end of the two minute drill Good luck Copyright 2005 Ted "Smitty" Smith

Further More Remember do not worry about writing down the right answer for now. When you reach the end all of the slides will be repeated without the timer so you can take your time to find the ones you missed and write down the correct answers then. This presentation is set up with varying time limits. Click on the slide to proceed. Copyright 2005 Ted "Smitty" Smith

Grounding Nonconductive coatings such as paint shall be removed from threads and other contact areas on equipment to be grounded. True False Copyright 2005 Ted "Smitty" Smith

Grounding True   250.12 Copyright 2005 Ted "Smitty" Smith

Equipment An appliance is rated 1200VA at 208 volts, three phase. It is a cord and plug connected. The cord plug and receptacle are not accessible from the location of the appliance. The disconnecting means for the appliance is the circuit breaker located in the panel. The panel is installed 65 feet from the appliance and can be seen when standing at the appliance. The circuit breaker can be locked in the open temporarily by use of a breaker lock out supplied by the manufacturer. Is this an acceptable installation? Copyright 2005 Ted "Smitty" Smith

Equipment No   422.33 requires the cord and plug to be accessible. If not accessible it refers you back to 422.31(B). 422.31(B) allows the breaker to be the disconnecting means if the breaker is within sight from the appliance or has a permanent means of locking the breaker open that remains in place regardless of whether the lock is in use or not. Article 100 defines “within sight from” as being within 50 feet of the appliance. This is located 65 feet away so it is not within sight from. The breaker can be locked out but only temporarily. This installation would require a separate disconnecting means. Copyright 2005 Ted "Smitty" Smith
