Fortunately, you CAN summon mountains beneath your feet. And get filthy stinkin' rich. The dissipation of energy and relative calm water created in the lee of the breakwaters often encourage accretion of sediment as per the design of the breakwater scheme.
However, this can lead to excessive salient build up, resulting in tombolo formation, which reduces longshore drift shoreward of the breakwaters.
This trapping of sediment can cause adverse effects down-drift of the breakwaters, leading to beach sediment starvation and increased coastal erosion.
This may then lead to further engineering protection being needed down-drift of the breakwater development. Salient formations as a result of breakwaters are a function of the distance the breakwaters are built from the coast, the direction at which the wave hits the breakwater, and the angle at which the breakwater is built relative to the coast.
Of these three, the angle at which the breakwater is built is most important in the engineered formation of salients. The angle at which the breakwater is built determines the new direction of the waves after they've hit the breakwaters , and in turn the direction that sediment will flow and accumulate over time.
There are two main types of offshore breakwater also called detached breakwater : single and multiple. Single, as the name suggests, means the breakwater consists of one unbroken barrier, while multiple breakwaters in numbers anywhere from two to twenty are positioned with gaps in between — feet or 50— metres.
The length of the gap is largely governed by the interacting wavelengths. Breakwaters may be either fixed or floating, and impermeable or permeable to allow sediment transfer shoreward of the structures, the choice depending on tidal range and water depth.
Their design is influenced by the angle of wave approach and other environmental parameters. Breakwater construction can be either parallel or perpendicular to the coast, depending on the shoreline requirements.

For example, a circuit breaker with a ampere "frame size" might have its overcurrent detection set to operate at only amperes, to protect a feeder cable.
The circuit breaker is labeled with the rated current in amperes , but excluding the unit symbol, A.
Instead, the ampere figure is preceded by a letter, B , C , or D , which indicates the instantaneous tripping current — that is, the minimum value of current that causes the circuit breaker to trip without intentional time delay i.
For the protection of loads that cause frequent short duration approximately ms to 2 s current peaks in normal operation.
For the protection of loads such as semiconductor devices or measuring circuits using current transformers. Circuit breakers are also rated by the maximum fault current that they can interrupt; this allows use of more economical devices on systems unlikely to develop the high short-circuit current found on, for example, a large commercial building distribution system.
In the United States, Underwriters Laboratories UL certifies equipment ratings, called Series Ratings or "integrated equipment ratings" for circuit breaker equipment used for buildings.
Power circuit breakers and medium- and high-voltage circuit breakers used for industrial or electric power systems are designed and tested to ANSI or IEEE standards in the C37 series.
Many classifications of circuit breakers can be made, based on their features such as voltage class, construction type, interrupting type, and structural features.
Low-voltage less than 1, V AC types are common in domestic, commercial and industrial application, and include:.
The characteristics of low-voltage circuit breakers are given by international standards such as IEC These circuit breakers are often installed in draw-out enclosures that allow removal and interchange without dismantling the switchgear.
Large low-voltage molded case and power circuit breakers may have electric motor operators so they can open and close under remote control.
These may form part of an automatic transfer switch system for standby power. Low-voltage circuit breakers are also made for direct-current DC applications, such as DC for subway lines.
Direct current requires special breakers because the arc is continuous—unlike an AC arc, which tends to go out on each half cycle, direct current circuit breaker has blow-out coils that generate a magnetic field that rapidly stretches the arc.
Small circuit breakers are either installed directly in equipment, or are arranged in a breaker panel.
The DIN rail -mounted thermal-magnetic miniature circuit breaker is the most common style in modern domestic consumer units and commercial electrical distribution boards throughout Europe.
The design includes the following components:. Solid-state circuit breakers , also known as digital circuit breakers are a technological innovation which promises advance circuit breaker technology out of the mechanical level, into the electrical.
This promises several advantages, such as cutting the circuit in fractions of microseconds, better monitoring of circuit loads and longer lifetimes.
Magnetic circuit breakers use a solenoid electromagnet whose pulling force increases with the current. Certain designs utilize electromagnetic forces in addition to those of the solenoid.
The circuit breaker contacts are held closed by a latch. As the current in the solenoid increases beyond the rating of the circuit breaker, the solenoid's pull releases the latch, which lets the contacts open by spring action.
They are the most commonly used circuit breakers in the USA. Thermal magnetic circuit breakers , which are the type found in most distribution boards in Europe and countries with a similar wiring arrangements, incorporate both techniques with the electromagnet responding instantaneously to large surges in current short circuits and the bimetallic strip responding to less extreme but longer-term over-current conditions.
The thermal portion of the circuit breaker provides a time response feature, that trips the circuit breaker sooner for larger over currents but allows smaller overloads to persist for a longer time.
This allows short current spikes such as are produced when a motor or other non-resistive load is switched on. With very large over-currents during a short-circuit, the magnetic element trips the circuit breaker with no intentional additional delay.
A magnetic-hydraulic circuit breaker uses a solenoid coil to provide operating force to open the contacts. Magnetic-hydraulic breakers incorporate a hydraulic time delay feature using a viscous fluid.
A spring restrains the core until the current exceeds the breaker rating. During an overload, the speed of the solenoid motion is restricted by the fluid.
The delay permits brief current surges beyond normal running current for motor starting, energizing equipment, etc. Short-circuit currents provide sufficient solenoid force to release the latch regardless of core position thus bypassing the delay feature.
Ambient temperature affects the time delay but does not affect the current rating of a magnetic breaker. Large power circuit breakers, applied in circuits of more than volts, may incorporate hydraulic elements in the contact operating mechanism.
Hydraulic energy may be supplied by a pump, or stored in accumulators. These form a distinct type from oil-filled circuit breakers where oil is the arc extinguishing medium.
To provide simultaneous breaking on multiple circuits from a fault on any one, circuit breakers may be made as a ganged assembly. This is a very common requirement for 3 phase systems, where breaking may be either 3 or 4 pole solid or switched neutral.
Some makers make ganging kits to allow groups of single phase breakers to be interlinked as required. In the US, where split phase supplies are common, in branch circuits with more than one live conductor, each live conductor must be protected by a breaker pole.
To ensure that all live conductors are interrupted when any pole trips, a "common trip" breaker must be used.
These may either contain two or three tripping mechanisms within one case, or for small breakers, may externally tie the poles together via their operating handles.
Three-pole common trip breakers are typically used to supply three-phase electric power to large motors or further distribution boards.
Separate circuit breakers must never be used for live and neutral, because if the neutral is disconnected while the live conductor stays connected, a very dangerous condition arises: the circuit appears de-energized appliances don't work , but wires remain live and some residual-current devices RCDs may not trip if someone touches the live wire because some RCDs need power to trip.
This is why only common trip breakers must be used when neutral wire switching is needed. These are often used to cut the power when a high risk event occurs, such as a fire or flood alarm, or another electrical condition, such as over voltage detection.
Shunt trips may be a user fitted accessory to a standard breaker, or supplied as an integral part of the circuit breaker. Air-break circuit breakers replaced oil-filled units for indoor applications, but are now themselves being replaced by vacuum circuit breakers up to about Like the high voltage circuit breakers described below, these are also operated by current sensing protective relays operated through current transformers.
Medium-voltage circuit breakers nearly always use separate current sensors and protective relays , instead of relying on built-in thermal or magnetic overcurrent sensors.
Medium-voltage circuit breakers may be connected into the circuit by bolted connections to bus bars or wires, especially in outdoor switchyards.
