What is the lug temperature rating of a breaker?
Look at the faceplate. There should be a 75˚C or 60˚C rating bsed on the temperature rating of the terminals. You have to use the lowest rating shown, ie, if you use 90˚C cable with a 75˚C termination, you have to derate the cable ampacity to a 75˚C. An example is look at 310.15(B)(16) in the 2011 NEC. 500kcmil cable is good for 430A in this table at 90˚C, if you had to derate to 75˚C, you loose 50 Amps and derate to 380A.
How can a class C fire be extinguished?
By an extinguisher with a C rating. The C just means the extinguisher can be used on a live electrical fire.
What is a meaning of star rating in air conditioners?
The star rating is provided for customer awareness by BEE (Bureau of Energy Efficiency.) EER stands for Energy Efficiency Ratio.Example:One 1.5 ton AC have 5275watts cooling capacity and 1650Watts power consumption, so EER of unit is 5275/1650=3.1 EER.As per the below table, this unit is 4 star rated.Star Rating Band Valid from 01 Jan 2008 to 31 December 2009EER (W/W)Star RatingMaximumMinimum1 Star2.502.692 Star2.702.893 Star2.903.094 Star3.102.295 Star3.30
What is mean rating?
This is the average rating. Basically add everything up and divide by the number of x. For example u have a=10,b=20,c=30... .the answer would be 30 divided by 3, which would be 10. Thus the mean rating would be 10
How many amps does a 175 watt mercury vapor light use?
depending on voltage supplying the bulb, each ballast spicifies on it such rating. many ballasts have better efficiency at higher voltage. however; say 175 watt bulb, 120V with 80% efficiency= (175/120)/.8=1.82amps
Is seer or hspf more important?
It depends what you use more, A/C or heat. The SEER rating pertains to cooling efficiency. The HSPF pertains to heating efficiency.
What does 'eff' mean in basketball?
Efficiency rating: ((PTS + REB + AST + STL + BLK) - ((FGA - FGM) + (FTA - FTM) + TO)) / G
What is the efficiency rating of a high efficiency furnace?
The efficiency rating is called annual fuel utilization efficiency or afue. For residential systems in the USA, the minimum is 80%. There is no standard for what is considered "high efficiency". The range of efficiencies goes up to about 96% for gas furnaces.
Is the true efficiency in a heat pump greater or smaller then the efficiency based on the motor?
It is greater. You need to look for the SEER (Seasonal Engergy Efficiency Rating) to see the true engergy rating of the heat pump.
What is the energy efficiency rating of the Frigidaire FAX052P7A?
9.7
