Question 1: Total General Lighting and Receptacle Load
Question代写 General lighting load = 3,800 Sq. ft. x 3 VA = 11400 VA Small-appliance branch circuit load = 3 Appliance Circuits x 1500 VA
General lighting load = 3,800 Sq. ft. x 3 VA = 11400 VA
Small-appliance branch circuit load = 3 Appliance Circuits x 1500 VA = 4500 VA
Laundry branch circuit load. = 1 Laundry Circuit x 1500 VA= 1500 VA
Total General Lighting and Receptacle Load = 11400 + 4500 + 1500 = 17,400 VA
Applying demand factors to the general lighting load.
Remainder at 35% = (17,400 - 3,000) x 0.35 = 5040 VA
TOTAL General Lighting and Receptacle Load = 3000+5040 = 8040 Question代写
Question 2: Fixed-in-Place Appliance Load Question代写
Water heater 28 kVA = 28000 VA
Dishwasher =1,200 VA
Food Disposal =1,200 VA
Attic Fans =1,500 VA
Total =31,900 VA
75% of total; for 4 or more appliances = 0.75 x31900 = 23,925 VA
Question 3: Dryer Load
Clothes Dryer: 5 Kw = 5000VA
Question 4: Cooking Equipment Demand Load
12kw demand factor is 80%
Equipment demand load = 12 x 0.8 = 9.6 kW = 9600 VA

Consider the AC unit as a motor load. Show your calculations on the lines provided for Question 6 at the end of Part 1 of your project. Graded Project 55
Question 7: Total Demand, Service Size and Service Conductors Based on your calculations for questions 1–6,determine the total demand in VA for this residence, the minimum service size, and the minimum conductor sizes (THW) for the ungrounded and grounding electrode conductors (assume the neutral conductor to be the same as the ungrounded conductor). Show your calculations on the lines provided
Question 8: Which article of the NEC describes the proper placement of outlets in this type of room?
Article 210. Question代写
Question 9: Part 1: According to the NEC, what is the maximum wall space that’s allowed between two adjacent outlets?Question代写
Part 2: How large must a wall space be to require an outlet?Question代写
Part 3: Should an outlet located at 7-feet up the wall from the floor, used to power a light fixture, be included in wall space requirement? No
Question 10: If the outlets in this room are supplied by a single 15A or 20A circuit, what is the maximum current that can be supplied (in amps) to a cord-and-plug connected load?
Should not exceed 80 percent of the branch-circuit ampere rating
Therefore = 20 x 0.8= 16 A
Question 11: Look at the items listed in Table 1.
Indicate which items are considered to be wall space by the NEC, and which items aren’t considered to be wall space. (Place an “X” in the appropriate column next to each item.)
Considered to Be
Not Considered to Be
|Fixed glass panel||X|
|Sliding segment of the glass door||X|
|Wall space less than 1 foot wide||Question代写||X|
|Wall space 3 feet wide||X|
