Circuit ProtectionRCD selectionA Residual Current Device (RCD) is a device that breaks an electrical circuit to prevent seriousharm from an electric shock, providing a level of personal protection. There are a numberof different RCDs available and selecting the appropriate device depends on the applicationthat it is being used to protect.RCDs react differently depending on the presence of DC residual currents and frequencieswhich occur for example in installations that feed electric vehicle chargers or solar panels.For guidance on the different types of RCD generally available and the currentsand applications these support, please refer to the table below.RCD TypeAC CurrentsType ACType AType FType B4AlternatingsinusodialresidualcurrentDC CurrentsApplicationsN/AGeneral purpose useResidual pulsating direct currentapplications up to 6mAAs Type AC as well as equipmentincorporating electronic componentsResidual pulsating direct currentapplications up to 10mAAs Type A as well as equipmentincorporating frequency controlledspeed drivesSmooth direct current applicationsup to 0.4 times the rated residual current(IΔn) or 10mA, whichever is the greaterAs Type F as well as electric vehiclechargers, PV supplies
Overload protectionWhen deciding the current rating of an RCD, consideration should be given to the rating of the OCPD(over current protective device) and not just on applying diversity factors to the downstream circuits(536.4.202).Consideration should also be given to whether additional circuits will be added in the future as this willchange the design current of the original electrical installation.Consumer unit designs where the current ratings of the Main Switch and RCD are equal to or greaterthan the service cut-out OCPD will ensure the regulation requirement is metSurge protectionElectronic equipment can be easily damaged by transientover voltages of atmospheric origin (e.g. lightning strikes) orswitching over voltages generated by equipment within theinstallation. Protection of equipment is required where theconsequence of it being damaged could: Result in serious injury or loss of human lifeInterrupt public services and/or damage cultural heritageInterrupt commercial or industrial activityAffect a large number of co-located individualsA Surge Protection Device (SPD) provides protection againsttransient over voltages which can result in premature agingor destruction of electronic equipment. These devices arestrongly recommended for installations exposed to transientover voltages where sensitive and expensive electronicequipment is installed.5

Series Circuit A series circuit is a closed circuit in which the current follows one path, as opposed to a parallel circuit where the circuit is divided into two or more paths. In a series circuit, the current through each load is the same and the total voltage across the circuit is the sum of the voltages across each load. NOTE: TinkerCAD has an Autosave system.
circuit protection component which cars he a fusible link, a fuse, or a circuit breaker. Then the circuit goes to the circuit controller which can be a switch or a relay. From the circuit controller the circuit goes into the circuit load. The circuit load can be one light or many lights in parallel, an electric motor or a solenoid.

The most common electrical circuit faults you will encounter when working on bus electrical systems are: open circuits; short circuits; and high resistance. Open Circuit - any break (open) in the current path of a series circuit makes the entire circuit inoperative. In a parallel circuit, only the branch effected by the open is inoperative.
Electrical Infrastructure includes an electrical installation, electrical equipment, electrical line or associated equipment for an electrical line. 1.9 Electrical installation As per the Electrical Safety Act 2002 (s15) (a) An electrical installation is a group of items of electrical equipment that—
