Electrical Inspection Checklist Before Buying a Property
Electrical Inspection Checklist Before Buying a Property purchasing a home is one of the largest financial choices that you can make. When buying a house, customers tend to concentrate on the place, building quality, flooring, plumbing, paint and inside, however one important space that is often neglected is the electrical system.
A standard home inspection might not detect electrical issues. If there are any electrical issues such as faulty wiring, overloaded wiring or circuits, poor earthing, damaged sockets, or inadequate electrical protection, it can pose safety hazards and result in costly repairs after moving in.
This is why an electrical inspection checklist before buying a property is important for identifying potential electrical issues before they become costly problems.
When you are looking to purchase a new apartment, resale flat, independent house, villa or investment property, it is essential that you review the electrical system as part of your property due diligence.
Why Is an Electrical Inspection Checklist Important Before Buying a Property?
Electrical systems are typically hidden within walls, ceilings and floors. This places an ordinary purchaser at a disadvantage to know if the wiring and electrical pieces have been installed properly.
There are cases where a property might appear to be finished, but suffers from issues like:
- Wrong or inadequate earthing
- Loose electrical connections
- Damaged wiring
- Overloaded circuits
- Worn-out MCB/safety devices
- Worn out switches and sockets.
- Exposed wires
- Improper electrical installations
- Signs of overheating
High load appliances connected in an unsafe manner.
These issues can go undetected and lead to common power surges, damage to appliances, electric shock and, in extreme situations, fire.
Using a proper electrical inspection checklist, a buyer can evaluate the most important electrical components in a systematic way before deciding to purchase a car.
Electrical Inspection Checklist Before Buying a Property
Use this electrical inspection checklist to review the key electrical components before buying a property.
Look at the Main Electrical Panel. Inspect the Main Electrical Panel.
Work from the main distribution board (also called the electrical panel).
Check whether:
- The panel is installed correctly and easily accessible.
- Circuits are well labelled.
- Correct installation of MCBs.
- No loose wires are present.
- There are no signs of overheating or burning.
- The panel is dry and rust free.
- The internal wiring of the panel has been adequately terminated.
A poorly organised, or poorly maintained, electrical panel might be an installation or maintenance problem.
Check Electrical Wiring
One of the most crucial aspects of reviewing is the condition of electrical wiring.
Search for indications of:
- Damaged insulation
- Exposed wires
- Loose connections
- Burn marks
- Melted insulation
- Improper joints
- Temporary wiring
- Cables that are old or out of good condition.Rusty or aged cables.
Older properties should be given special consideration in terms of condition and capacity of existing wiring.
If wiring is hidden, professional testing might be required as it’s not possible to see all problems by looking.
Earthing and Grounding
Earthing is a critical aspect of electrical safety.
The earthing system may offer a safe means of current flow in the event of a fault and may help minimize the potential for electric shock.
Check earthing arrangements are available and operating at electrical inspection.
Electrical measurements may be carried out as part of a professional inspection to assess if the system is operating safely.
Check MCB, RCCB and Other Safety Devices
Appropriate protective devices should be provided on modern property, in accordance with the electrical system and requirements.
Check the condition and operation of devices such as:
- MCBs
- RCCBs/RCDs
- RCBOs
- If available, use surge protection devices.
The protection is of particular importance for RCCB/RCD types which can be used to protect from electric shock due to leakage current.
Installation of a protective device does not ensure a safe electrical system. It should also be determined whether it is in good or bad condition, and if it was properly installed and operated.
Test Switches and Sockets.
All accessible switch and socket should be tested.
Look for:
- Loose switches
- Cracked plates
- Broken sockets
- Discolouration
- Sparking
- Excessive heat
- Loose connections
- Improperly fitted outlets
Where applicable, the polarity and other electrical characteristics of sockets should also be checked.
Remember to pay special attention to sockets that are used by high power appliances like air conditioners, geysers, ovens and washing machines.
Check for Burned Out Light Fuses
There are numerous high power appliances in modern homes.
Electrical systems can be put under strain by air conditioners, geysers, induction cooktops, refrigerators, washing machines and other appliances.
At the time of the inspection, ascertain if circuits are designed appropriately for their load.
Some indicators are:
- Frequent MCB trips
- A permanent extension board being used.
- Two or more appliances that are connected to the same outlet and have a high demand.
- Hot sockets
- Flickering lights
- Burning smells
These are indications that should not be overlooked.
Inspect Lighting Points
Inspect accessible light points on premises.
Check for flickering lights, loose fittings, and broken outlets as well as any inconsistent operation.
If lights blink often, there’s a reason and it should be determined.
Document the results of the checks.
Record the results of the checks.
If there is a high load appliance in a property, it should have adequate electrical provisions.
Make sure connections and dedicated points are checked for:
- Air conditioners
- Geysers
- Washing machines
- Ovens
- Microwaves
- Induction cooktops
- Dishwashers
- Water pumps
- Other large electrical gear
The capacity and safety of the electrical equipment that supplies these appliances should be appropriate for the appliances to be operated.
Check the cooking appliances
The kitchen is equipped with various electrical appliances and needs special attention.
Inspect sockets and circuits around:
- Refrigerator
- Microwave
- Chimney
- Oven
- Dishwasher
- Water purifier
- Induction cooktop
Electrical outlets need to be located and prevented from potential contact with water.
Do not use temporary wiring or use extension boards as a permanent fix.
Check Bathroom Electrical Safety
Bathrooms may need special attention since there’s an added potential for safety issues with electricity and water.
Check readily visible electrical fittings, switches, exhaust fans, geyser connections and other electrical systems.
Ensure that electrical installations are suitably located clear of areas where direct water contact may be possible.
Special attention should be paid to geyser wiring and protection.
Check Outdoor Electrical Points
Balconies, gardens, terraces, parking areas and external electrical points, if present, should be checked.
Check for:
- Exposed wiring
- Damaged outdoor sockets
- Loose fixtures
- Water exposure
- Improper cable protection
- Corrosion
Moisture and weather conditions can cause outdoor electrical installations significant damage.
Test Inverter, UPS and Generator Connections
In the case of an inverter, UPS or generator connection, check that the connection is installed correctly.
Back-power connections can pose safety issues and lead to unwanted back-feeding into circuits if it is not performed properly.
These installations must be evaluated by a competent professional, if required.
Common Electrical Defects Found in Properties
Some electrical problems are more prevalent than others during the time of a property inspection.
These may include:
The poor and inadequate earthing condition.
Earthing practices can pose an electrical risk if not done correctly, and should be evaluated by an expert.
