In order to refine and define theoretical weights, researchers added frame size as a factor. The sizes are categorized into three categories:- Small frame, medium frame and large frame. The reason for this is that obviously bone structures vary in size and density from person to person. Equally obviously men and women have different structures. Bone mass and muscle mass all play a part in determining your optimal weight. Large boned people. There are two simple methods of determining frame size:-
- Measuring the circumference of your wrist. This is by far the most straight forward.
- Measuring the breadth of your elbow. This is a little more complex but provides a greater results range for the purposes of accuracy.
In order to do this:-
Stand up. Extend your arm forward so that it is horizontal and parallel to the ground. Turn your hand so your palm is uppermost. Bend your elbow so your forearm is at 90º to the ground. Use the forefinger and thumb of your other hand to locate the narrow part of your elbow joint. Use your same forefinger and thumb as a guage to determine your elbow breadth by measuring the gap between them with with a ruler or tape measure. Compare the value with the tables below.
(Less than 155cms) Height 5'2"-5'5"
(155cms-163cms) Height more than 5'5"
(More than 163cms) Small Less than 5.5"
(140mm) Less than 6.0"
(152mm) Less than 6.25"
(159mm) Medium 5.5"-5.75"
(140-146mm) 6"-6.25"
(152-159mms) 6.25"-6.5"
(159-165mm) Large More than 5.75"
(146mm) More than 6.25"
(159mm) More than 6.5"
(165mm)

How do you determine a bodys frame size?
height
How To determine your body frame size?
To determine your body frame size, measure the size of your wrist. Large boned people will have a larger circumference wrist than a small boned person. Once you determine your bone structure, you should take that into consideration when determining your ideal weight.
For circuit breaker what does it mean by AF AT?
AF refers to the ampere rating of the breaker frame and AT refers to the breaker trip rating in amps. These are not breakers that you would find in your home but industrial molded case breakers. The current trips can be changed out to different values all within the same frame size.
What is the meaning of 200AT-250AF in circuit breaker?
250AF refers to the ampere rating of the breaker frame and 200AT refers to the breaker trip rating in amps. These are not breakers that you would find in your home but industrial molded case breakers. The current trips can be changed out to different values all within the same frame size.
What is the meaning of 200AT 250AF in circuit breaker?
250AF refers to the ampere rating of the breaker frame and 200AT refers to the breaker trip rating in amps. These are not breakers that you would find in your home but industrial molded case breakers. The current trips can be changed out to different values all within the same frame size.
How are Branch circuit protected?
Branch circuits are protected by the circuit breaker found in the electrical panel. Each circuit should have its one breaker. The breaker should be rated to protect the insulation of the wire, so you can determine the breaker size based on the circuit conductor size Example #14-2 should be protected by a 15 amp breaker
How do you determine what size body frame a woman has?
If you use your fingers around the wrist and see if the fingers touch, the person has regular body frame size. If the fingers overlap, the fame is small. If the fingers do not meet, the frame is large.
What size wire and breaker do you need for a 5000 watt garage heater?
Look on the heater and see what amps it is pulling. That will determine the wire size and breaker size. It must be on a dedicated circuit. 15 amps = AWG # 14 wire with 15 amp breaker 20 amps = AWG # 12 wire with 20 amp breaker 30 amps = AWG # 10 wire with 30 amp breaker 40 amps = AWG # 8 wire with 40 amp breaker
What meaning of 63at-125af in electrical parameters?
AF refers to the ampere rating of the breaker frame and AT refers to the breaker trip rating in amps. These are not breakers that you would find in your home but industrial molded case breakers. The current trips can be changed out to different values all within the same frame size
When installing a circuit breaker do you size the breaker to correct wire size or the device its controlling?
When installing a circuit breaker, you size the breaker based on the wire size. The breaker should be matched to the ampacity of the wire to ensure proper protection against overloads and short circuits. The device being controlled by the breaker is not a determining factor in sizing the breaker.
Which circuit breaker to use for the plugs and geysers?
It is recommended to use a circuit breaker with a rating of 15-20 amps for plugs and geysers in residential homes. However, it is important to consult an electrician to determine the appropriate circuit breaker size based on the specific electrical load requirements of your plugs and geysers.
What is the standard to select circuit breaker?
Add up your amps to calculate your breaker size. Add up your loads (amps), divide by 0.8, and choose that size breaker. If that number does not correspond to a standard size breaker you go to the next higher standard size breaker.
