No property in the world is void of an electrical system in place. The process of connecting the components of such a complex system—for its fruitful and effective operation—is what is known as electrical installation.
It is safe to say that dodging significant electrical failures during installation is a prerequisite, and ensuring that its execution is safe and sound can determine whether or not both the homeowner and home occupants are protected from potential electrical hazards.
In this blog, we will discuss the most common mistakes that can be found during electrical installation. Becoming aware of the actual problem and where it stems from will be the first step towards evading faulty installations once and for all.
What are the Most Common Mistakes to Avoid in Electrical Installation?
We will now explore in-depth the most well-known mistakes that may show up while going about electrical installation.
Lack of Prior Planning
First of all, an electrical installation will not be as successful as intended without sufficient preparation and planning beforehand.
Here is what a lack of preparation before installation can look like:
- Not buying all the rudimentary items needed for the procedure from the very beginning.
- Not acquiring all the necessary permits.
- Not carrying out important inspections.
- Not having a clear vision of where each component will go.
Neglecting a proper plan from the start, regarding how to get your electrical installation done, will inevitably make you risk wasting time and money on future repairs.
Poor Electrical Wiring
The second mistake that can emerge is an improper management of wiring during electrical installation. This can lead to undesirable electrical issues or hazards, such as:
- Electrical shocks
- Electrical fire risks
- Appliance damage
- Tripped circuit breakers
- Burning smell
- Electrical sparks
- Flickering lights
- Discolouration
Some of the most common representations of incorrect electrical wiring include:
Using the wrong wire gauge or type
A wrong wire gauge means that an incorrect wire thickness has been used. This is a critical mistake that can lead to electrical fires, overheating, or short circuits.
Using plastic insulation on hot wires
Even though plastic is an insulator, it is inappropriate for very hot or high-current wires, as it can’t handle that much heat.
Incorrect system grounding and bonding
Proper grounding allows for a safe path for electricity to flow and connect to the earth; otherwise, dangerous voltage buildup may take place, which can be a serious electrical hazard.
Similarly, bonding is the connection of metal parts together to make sure they are at the same electrical potential. If that does not happen properly, electrical dangers will ensue.
Loose or faulty wire connections
This mistake can lead to flickering lights, power failures, and more. Loose wire connections might arise from improper installation, corrosion, vibration, ageing, or thermal expansion and contraction.
Exposed wiring
When the protective insulation surrounding a wire is damaged or missing, this results in the exposure of a live wire, which is very dangerous.
Overloaded circuits
If too many devices are connected to a single circuit, this will lead to an electrical load. This draws more current than can be safely handled, making hazards occur.
Overcrowded electrical boxes
If plenty of wires are crammed and overcrowded in a single electrical box (where heat dissipation does not get a chance to occur) can lead to countless hazards.
As you can see, it is easy to mess up with wiring during installation; beware of its countless manifestations and avoid them at all costs.
Unprotected Cables
Another popular mistake in electrical installation is leaving your cable unprotected. Similar to bad electrical wiring, unprotected cables can pose fire risks, electric shocks, damage to equipment, and much more.
Being Inattentive to Labels and Markings
When it comes to the labels and markings on electrical components, not paying attention to them can result in major issues in electrical installation, such as severe injuries or even death.
Since they carry critical safety information (like the voltage, current, and usage limits for each component), it is important that you resort to them during installation for safety and protection.
Bad Electrical Switch and Outlet Placement
The placement of the switch and outlet is a crucial aspect to consider to avoid electrical installation problems.
Avoid placing outlets too high or too low, ensuring a convenient location to be able to easily plug in any appliances or devices. Similarly, switches should also be located in a user-friendly place and be realistically reachable.
Improper GFCI Protection
Poor GFCI (Ground Fault Circuit Interrupter) protection and electrical installation can be a palpable mistake. Compromising the protection of GFCI increases the risks of fires and electrical shocks.
One of the fault approaches that people make is to install standard outlets in damp locations, where GFCIs should be located instead.
Insufficient Safeguards Against Power Surges
Not investing in proper protection against electrical surges can be a huge electrical installation mistake. Some beneficial safeguards include:
- Surge Protective Devices (SPD)
- Consulting with a licensed electrician
- Unplugging sensitive electronics
Poor Installation of Lighting Fixtures
Improperly installing lighting fixtures is one of those electrical installation mistakes that should not be taken for granted. Such an error can lead to overheating, aesthetic concerns, functional issues, fire hazards, and more.
Disregarding Local Electrical Codes and Regulations
Electrical codes and regulations, such as the National Electrical Code (NEC), exist for safety and protection in mind. When electrical codes are intentionally ignored during an electrical installation, a few issues may occur:
- Legal penalties
- Fines
- Insurance issues
- Property selling challenges
- Safety hazards
Overlooking Regular Maintenance and Inspections
Underestimating the power of regular maintenance and inspection is only going to aggravate electrical problems.
There are so many benefits of perpetual maintenance and inspection. Here are some of them:
- Issue detection early on
- Electrical hazards’ avoidance
- Extension of equipment lifespan
- Compliance with safety codes and regulations
Not Testing the Electrical System
Finally, one of the most common electrical installation errors is not testing your electrical system during and after installation. Here is why putting your electrical system to the test is crucial:
- Troubleshooting
- Compliance
- Safety and protection
It is also worth noting that you should always be sure that there is no excessive voltage going through the electrical system whenever you are testing it.
What to Do If You Discover an Electrical Issue?
It is recommended that you don’t deal with electrical hazards, and electrical installations for that matter, completely alone.
This is because the ordinary person won’t have the experience or the expert knowledge required in these situations that a professional has.
Contacting an emergency electrician right away when electrical dangers or concerns arise is the safest and most effective way to go about it.
Electrical Certificates that All Electricians Should Have
Experienced electricians should obtain prominent electrical certificates, as this will guarantee the rarity of an electrical issue emerging in the first place.
The different types of the most significant electrical compliance certificates include:
Electrical Installation Certificate (EIC)
An EIC is a document that a professional electrician issues to verify that the electrical installation work they will carry out complies with safety regulations and standards.
Minor Electrical Installation Works Certificate (MEIWC)
This certificate confirms that any minor work done by a certified electrician—in terms of electrical installation—adheres to electrical codes and safety regulations.
Examples of such minor work include adding a socket outlet or installing a fused spur.
NAPIT Certificate
The NAPIT certificate indicates that an electrician has been approved and accredited by the National Association of Professional Inspectors and Testers (NAPIT), which is a UK-based organisation.
Being NAPIT certified reinforces that an electrician has met the appropriate standards for both competence and safety.
NICEIC Certificate
Issued by the National Inspection Council for Electrical Installation Contracting (NICEIC), this certificate is essential for all qualified electricians to acquire.
NICEIC-registered contractors are highly trustworthy, given that such a reputable certificate testifies to the fact that an electrician is well-equipped to carry out professional electrical work.
