The unlimited J test is nothing like a master exam. Basic calculations and ohms law. PSI has a practice test.
Here in OK you need Unlimited J test and the contractors is how to run a business and pay you taxes.
If you have been accepted to test PSI will be your source for code book year and uglys book. Remember to use 1.732 and not 1.7 as in the uglys
book. All open book question are word for word out of the NEC. a few ugly book questions, resistor color code and first aid with a few osha.
If you have taken a master this one is a breeze.
One horsepower is equal to how many watts?
What is an askarel?
A continuous load is a load where the maximum current is expected to continue for at least how long?
What is the formula for calculating power (watts)?
What is the minimum branch-circuit rating for ranges of 8-3/4 kW or more?
What is the maximum voltage drop for any branch circuit, separately derived system, operating at 120 volts line-to-line and 60 volts to ground, serving sensitive electronic equipment?
Receptacles in residential units shall be installed such that no point measured horizontally along the floor line of any wall space is more than how far from a receptacle outlet?
Temporary electric power and lighting installations for holiday decorative lighting shall be permitted for a period not to exceed how many days?
Plug fuses shall be permitted to be used in circuits supplied by a system having a grounded neutral point where the line-to-neutral voltage does NOT exceed which of the following?
For permanently connected appliances, the branch-circuit overcurrent device shall be permitted to serve as the disconnecting means for appliances rated at not over?
Which is best defined as an unintentional, electrically conductive connection between an ungrounded conductor of an electrical circuit and the normally non-current-carrying conductors, metallic enclosures, metallic raceways, metallic equipment, or earth?
A metal underground water pipe used as a grounding electrode shall be in direct contact with the earth for a minimum of how many feet?
If installed and routed on the outside of a raceway, the length of the equipment bonding jumper shall not exceed how many feet?
A minimum of how many threads needs to be engaged if machine screws are used to fasten bonding jumpers?
What is the maximum number of 12 AWG conductors that can be used in a 4" x 1-1/2" square box?

An appliance for a residence is rated at 30 amperes. It is continuously loaded and is not motor-operated. What is the minimum branch circuit rating that is required if the branch circuit device is not listed for continuous loading?
What is the approximate power loss for a conductor in a 208-volt circuit that has a 5% voltage drop with a current flow of 15 amperes?
A resistor has the following colored bands (in order): orange, red, brown, silver. What is the resistor value?
Just some sample questions you might see. This will give you an idea what there after. Most is covered right here on this site.
Just an idea what you will face. Then there always a farm load question. The answer is in the exception word for word.
No where near master level. We have such a high failure rate that every one says you cant pass first time out. I was like, your kidding, right. Plus you only need 75%
The unlimited J test is the same one used for contractors. Talk with your buddy's on what they saw on the test.
Good luck, Tulsa.
