WHAT IS DIfference between ANSI and ASTM F 2413-11?
ANSI is the American National Standards Institute. They coordinate the development of US Voluntary National Standards in private and public sectors with regards to information management and data communications. ASTM is the American Society for Testing and Materials. They develope, publish standards, definition of materials, methods for testing materials, installation practices and specifications for materials. Ok since ASTM develops the standards how does that affect OHSA standards to ANSI on safety ie.. Z87 stamp on safety glasses?
How much rating ammeter required in rcu for 75 kw motor?
200 amphere
Is the kva rating of a three phase generator per phase or a total of the three phases example is a 3 phase 75 kva generator 25 kva per phase or 75 per phase?
The kV.A (not 'kva') rating is the total apparent power of the machine. So a 75 kV.A machine is 25 kV.A per phase.
What is the amperage rating of 500 MCM copper conductor?
It depends on a lot of factors. Generally speaking, if the insulation is THHN then the rating is 350 amps. If the insulation is THWN then the rating is 310 amps. The ampere rating for wire depends on the temperature of the environment it will be used in, the insulation rating and the number of circuits installed in a conduit. There are also other factors to consider... like voltage drop in long runs.
What is the measurements of 75 kva transformer 3 phase?
For a single-phase transformer, divide the ratedapparent power (expressed in volt amperes) by the voltage rating (expressed in volts) of the primary winding; this will give you the rated primary current (expressed in amperes) of the primary winding.

What is the difference between ANSI steel toe and ASTM steel toes?
As of March 2005, ASTM F2413 standard superseded the ANSI Z41 standard. Manufacturers and distributors will implement a "running change" to their inventory from the ANSI Z41 labeled footwear. Because there is no change in the protocol, the ASTM F2413 standard does not require that the change from ANSI to ASTM labeled footwear occur in a specific time period.The protective footwear you choose must comply with the American Society for Testing and Materials (ASTM) standard F2413-05, formerly the American National Standards Institute's (ANSI) standard Z41-1999. The F2413-05 standard separates safety footwear into different categories such as Impact and Compression Resistance.ASTM F2413-05 - The letters F2413 reference the performance requirement for foot protection. The additional digits following the standard designation indicate the year of the standard to which the protective footwear complies, for example: 05 refers to 2005.M = Footwear designed for a male.F = Footwear designed for a female.I/75 = Impact rating of 75 (foot pounds)C/75 = Compression rating of 75 (2500 lbs. of pressure)The ASTM F2413 standard has two classifications for compression ratings 75 = 2,500 lbs and 50 = 1,750 lbs. This means the footwear has been tested to withstand compressive loads up to the designated number of pounds before the toe-cap will start to crush or crack.
What is the pressure rating for a Class 75 flange?
75 psig For pipe flanges the class rating is the pressure rating for the flange, in pounds per square inch - gauge (psig).
How does temperature affect power rating of carbon resistors?
Its normal power rating is at room temperature. For a temperature of 75 degrees, halve the rating.
Do lynxes eat berries?
No they do not. 75% of there diet is snow shoe hare
How much does it cost to resole shoes?
About $45 to $75 depending on the shoe and where you live in the country.
What is the Pressure rating of .75 black pipe?
Welded or screwed ot MJ?
How much points distributed for customer service by hay rating systems?
75 points

What is the value of a W H Goss Queen Victoria's Riding shoe?
There is no such item. There is a Queen Victorias First Shoe, (value £5 to £25 depending on crest) and a Queen Elizabeths Riding Shoe (value £20 to £75 depending on crest).
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.
