The Main Parts of an Electrical Inspection
Electrical inspections ensure your property’s wiring is up to code and safe. They also verify that you have enough circuits to handle the electricity your building uses.
GFCI outlets and AFCI breakers are required in areas where water might be present, and switches must be a certain height above the floor. A licensed contractors can confirm that these safety devices are in place and working correctly.
A major part of any electrical inspection involves looking at the wiring in a building. Inspectors will look at the types of wires used and the condition of those wires. They will also check for proper grounding and bonding. They will also look to make sure that all outlets are attached to a power source and that the wiring is not exposed in wet or damp areas. Inspectors will check to see that any circuit breakers or fuses are working properly and are the correct size for the load they carry. They will also check that all GFCIs and AFCIs (arc fault circuit interrupters) are functioning correctly.
The most in-depth type of electrical inspection is an EICR (Electrical Installation Condition Report). This more extensive test will involve turning off the electricity to a property and testing various circuits. This will identify any damage, deterioration and defects that cannot be seen with a visual inspection. It will also recommend improvements to the electrics of a building.
This inspection will reveal any circuits that are overloaded, potential electric shock risks and fire hazards. It will also highlight faulty DIY electrical work and lack of protective bonding. It will also show whether any equipment is not compliant with the current edition of BS 7671.
If a property is overdue for its electrical inspection, it’s a good idea to book one as soon as possible. The process should only take a few hours and will require the inspector to go room by room. In addition to checking the wiring, the inspector will also look at the condition of electrical fixtures and switches. They will also examine how the cables and wires are clamped in the boxes and ensure that there is enough space for future wiring changes. For example, the clamps should grip the sheathing of the cable and not the conducting wires themselves.
Faulty wiring is a leading cause of house fires. As such, an electrical inspection is vital for homeowners and landlords alike. By having an inspection done on your home or business, you can help to avoid a dangerous situation and potentially save lives.
Inspection of Circuit Breakers
Electrical circuit breakers are designed to prevent overheating in the event of a fault. Inspectors will check that they are working correctly to do this. They will also look for signs of deterioration and damage to the circuit breakers. They may also do tests to make sure the breaker is able to detect faults and trip as necessary. This testing includes:
Connection tests – this test checks that the circuit breaker is connected to its proper terminals and that the connections do not show evidence of overheating. Overload tripping tests – this test applies 300% of the breaker rating to see if it will open automatically under these conditions. Contact resistance tests – this test measures the resistance of each pole within the circuit breaker. This can detect unusual wear and tear that is not due to normal operation. Instantaneous magnetic tripping tests – this test ensures that the magnetic feature of the circuit breaker is able to detect a fault and trip as required.
The inspector will also examine the junction boxes to make sure they are properly labeled for safety and that non-qualified personnel know not to mess with them. They will look for any gaps or openings that need to be closed and that the cable clamps are gripping the cable sheathing, not the conducting wires themselves. They will also be looking for at least 8 inches of usable wire length extending from each box and that the wire gauge is appropriate for the amperage of the circuit (14-gauge wire for 15-amp circuits, 12-gauge wire for 20-amp circuits).
The inspector will then examine the settings on the circuit breakers to ensure that they are set up according to the original design specifications. This is done by using a digital logbook, such as Schneider Electric’s EcoStruxure Facility Expert, to record the details of the configuration of each device and perform a number of operational tests to check that the settings are functioning as intended. This can be performed either before or during the installation of the equipment. The results of these tests can then be used as a reference for future maintenance.
Inspection of Surge Protectors
A surge protector can help protect appliances and electronics from power spikes. However, if the device is not functioning correctly it can lead to fires and other electrical issues. During an inspection, the inspector will check the surge protector for signs of deterioration. This includes the wires wearing out and the physical damage to the device.
An electrician will also make sure that the surge protector has the proper capacity to handle the current running through it. If the device is not rated to handle the maximum amount of electricity it could send, this may cause overheating and short circuits. It is also important to check if the surge protector has any warning indicators. For example, it might have a red LED or it may emit a beeping sound when plugged in. If the indicator lights keep flickering it means that the surge protector is not working properly.
In addition to surge protectors, the inspector will check all outlets in the house. This includes GFCI outlets, which are required in bathrooms, kitchens, garages, basements, and other areas where there might be water. These devices will cut off the outlet from the power supply if they detect any irregularities.
While some people mistakenly believe that a surge protector is similar to a power strip, they are not the same. A power strip can provide only limited protection for sensitive equipment, such as fax and answering machines, televisions, computers, and satellite systems. A true surge protector is designed to prevent power surges that can destroy circuit boards and other delicate electronic components.
Although most homeowners do not think about the risks of surges, this type of power surge is one of the leading causes of home fires. A surge can carry tens of thousands of volts, which is enough to fry circuit boards and other delicate electronic components. To reduce the risk of a surge, every homeowner should have a surge protector installed in their home and use it to protect expensive electronics. Additionally, homeowners should have their homes inspected regularly by an experienced and licensed electrician to ensure that all wiring is in good condition.
Inspection of Electricity Leaks
The inspection of electricity leaks is one of the most important parts of an electrical inspection. If these leaks are not addressed, they can cause fires, electrocution and other dangerous situations. Often, these problems are caused by improper installation or the use of non-standard devices in the household.
The main goal of an electrical inspection is to ensure that all wires, circuit breakers and other equipment are working correctly. This can be accomplished by testing them for proper functioning and looking for any signs of damage or deterioration.
A qualified inspector will be able to identify any potential problems and can recommend repairs or improvements as needed. This is why it is so important to have an electrical inspection performed regularly to avoid costly problems down the road.
An electrical safety check, or an EICR (Electrical Installation Condition Report), is a standard procedure that helps to determine whether any installations are fit for purpose. This is a legal requirement for private landlords in England and Wales, but it is also a good idea for homeowners. The process of an EICR involves turning off the power to the installation being tested, and it usually includes checking various parts of the electrical system to look for any damage, deterioration or defects.
During an electrical inspection, the inspector will check for ground fault circuit interrupters (GFCIs) in bathrooms, garages and grade-level portions of unfinished accessory buildings, basements, kitchens, and wet-bar sinks. These devices are designed to shut off a circuit if they detect that it’s overloaded, which can prevent electrocution. Inspectors will also make sure that all outlets are properly plugged in and that they have the proper amount of wiring.
Another important aspect of an electrical inspection is making sure that all access points to the wiring are properly protected from physical damage and tampering by unqualified people. This means that the access panels for circuit breakers and other equipment need to be covered by locked doors, and any openings in the walls of a home or business need to be sealed with appropriate materials. Inspectors will also check that receptacles are properly labeled, so non-qualified personnel can’t mess around with them.
