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

Question 5: HVAC Load Determines the total AC load for the HVAC system in this residence.


Show your calculations on the lines provided for Question 5 at the end of Part 1 of your project.

Question 6: Largest Motor Load Determine the largest motor load for this residence. Do not

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

12 feet.

Part 2: How large must a wall space be to require an outlet?Question代写

2 feet

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.)
