what is the difference between single pd and dual pd?
5895
Single PD (or binocular PD) is the measurement from pupil to pupil between each eye. Dual PD (or monocular PD) is the measurement from your nose bridge to each eye. Dual PD is believed to be the most accurate since many people may find their nose-to-pupil measurement is not equidistant on both sides.

In the typical home, both sides of such a dual breaker will be of the same value, but not necessarily so in an RV. You can often get a suitable replacement breaker for a single or double of the same value at the hardware store, but if you can't find what you need, by all means, visit an RV supplier.

The basic difference between a combined single limit policy and a split limit policy is that the split limit requires multiple limitations to the policy while single limit coverage gives you one amount of coverage to use as needed for the expenses resulting from an auto accident.

"Single" means that a single connection is opened to measure the speeds. "Multi" means that multiple connections are used - usually anywhere from 3 to 8 - at the same time and measure the total speed across them all.

The difference between the single point and multi point is: A single point heater serves only one location, i.e, a sink, a basin etc. A multi point is generally a boiler that serves more than one draw off point in your home (a draw off point is controlled by a Tap/Faucet).

In full wave rectifier at a time only one diode will be ON ….. Bridge rectifier use four diodes and single winding transformer. Diodes are inexpensive (50 paisa each) center tapped transformer is more costlier than single winding transformer. In bridge rectifier the out put dc voltage is double that of full wave.

A single unit run capacitor hooks up to a single motor, and it is more commonly used in smaller HVAC systems, like small air conditioners. A dual run capacitor incorporates two capacitors into a single unit. With a dual run capacitor, you can power two electric motors.

DUAL PD, or monocular PD, consists of two numbers and is the distance between the centers of each pupil to the bridge of the nose. Dual PD is usually written in the following notation: 32/30. The first number is always the right eye (OD) measurement, and the second number is the left eye (OS).

So to conclude, the major differences between singles and doubles lie in the amount of time they burn for, as well as how long it typically takes to get them going. This, of course, makes trebles house coal a more price-efficient option than doubles, as you won't need to refuel your fire quite as often.

These RCDs must operate in all active and neutral conductors (the neutral must be switched). ... Where the socket outlets are supplied direct from permanent or hard wired (non-plug-in) switchboards, they may be single pole, however their circuit protecting RCD/ RCBO must be double pole.

Pupillary distance (PD) or interpupillary distance (IPD) is the distance measured in millimeters between the centers of the pupils of the eyes. ... Monocular PD refers to the distance between each eye and the bridge of the nose which may be slightly different for each eye due to anatomical variations.

120/208V single phase is derived from 208V three phase power. ... Since the two waveforms peak at different times, the combined power you get from them is less than the numerical sum of the two. When one waveform is at its peak, measuring 120V, the other is only part of way through its cycle, measuring only 88V.

Can I have multiple TPD claims? Yes, you can have multiple Total & Permanent Disability (TPD) claims as long as each of your current funds is independent from the other.

The difference between a twin and single pump is the number of impellers. Twin pumps are designed to supply both hot and cold water to showers, bathrooms and whole house installations, while single impeller pumps supply either hot or cold water, to single or multiple outlets.

DPDT. Adding another pole to the SPDT creates a double-pole, double-throw (DPDT) switch. Basically two SPDT switches, which can control two separate circuits, but are always switched together by a single actuator. ... A DPDT circuit symbol, and a 6-terminal DPDT rocker switch.

SPST simply mean single pole, single throw. The product controls one circuit with one On position. SPDT means that it is a single pole double throw which means it has two ON positions. ... DPST again means it controls two separate circuits but it only has one On position.

A split load has a number of ways that are protected by an RCD and a number of ways that arn't. This type of consumer unit was very common for installations carried out to the 16th edition of the wiring regulations. A dual RCD consumer unit has two independant RCD's, each protecting a number of ways (6+6 for example).
