When Should You Hire an Electrician?

5th March 2024

As a home or business owner, handling electrical issues yourself can seem like a money-saving tactic. However, once signs of electrical system trouble arise, knowing when to call in a professional becomes critical. Attempting hazardous DIY repairs often exacerbates underlying problems, leading to expensive damages.

This article outlines warning signs indicating your electrical wiring or components require assessment by a certified electrician. We discuss situations where electrical safety experts should handle installations. You’ll also learn actions to take during electrical emergencies, along with tips for ongoing preventative maintenance.

Equipping yourself with knowledge of when electrical tasks demand qualified technician skills versus handyman-level repairs protects your occupants, valuables and buildings from otherwise avoidable electrical disasters. Read on and take notes on these vital electrical service warning indicators.

Signs of Electrical System Failure

Some clear signs indicate your electrical system is failing or wiring is outdated. Being able to recognize these red flags can help prevent injury, fires, or extensive property damage.

Frequent Tripped Breakers or Blown Fuses

Circuit breakers and fuses are designed to trip or blow when too much current flows through a circuit. If you find yourself constantly resetting breakers or replacing fuses, it likely indicates an underlying electrical issue. Reasons for repeated tripping/blowing include:

Faulty wiring
Equipment drawing too much power
Too many items running on one circuit
Failing breaker or fuse

Any of these situations warrant hiring an electrician to inspect and repair wiring.

Flickering or Dimming Lights

Lights that constantly flicker or dim are likely pointing to a loose wiring connection or outdated electrical panel. Loose connections interrupt the electrical flow, while outdated panels can’t provide enough power for all your home’s needs.

Persistent flickering/dimming means wiring should be examined. An electrician can locate hazardous connection issues and recommend panel upgrades if necessary. Leaving these problems unattended risks lost power or electrical fires.

Odd Electrical Odors

Smelling burning plastic or smoky odors emanating from outlets, switches, or appliances indicates dangerous electrical issues. Potential causes include:

Damaged wiring insulation
Overheated electrical components/motors
Sparking connections

These odors often arise long before seeing smoke or fire. Having an electrician track down the source of strange smells can prevent disastrous electrical failures. Never ignore burning electrical odors inside your home or business.

Frequent Minor Outages

If you find certain lights or outlets in your home/business frequently losing power inexplicably, faulty wiring is likely the culprit. Sections of wiring may have damaged insulation or connections coming loose.

While brief outages may seem harmless, they usually worsen over time. Left unaddressed, minor outages can devolve into complete system failures. Contact an electrician to locate and repair compromised wiring before problems expand.

When Rewiring or Upgrades Are Needed

Beyond addressing issues with your current electrical system, there are situations where rewiring or upgrades become necessary:

Old or Outdated Wiring

If your home/building has wiring that is over 30-40 years old, rewiring should be considered. While properly maintained, older electrical systems can keep running safely, but insulation and connections decay over decades of use. Upgrading provides modern, reliable wiring resistant to overheating failures.

Having an electrician rewire using modern materials eliminates lurking fire hazards from obsolete electrical components. This also prepares a structure for handling higher electrical loads from large appliances and devices.

Remodeling Existing Spaces

When remodeling kitchens, bathrooms or any living spaces, hiring an electrician is crucial. Existing electrical systems almost always require modifications and additions to support reconfigured room layouts and new lighting/appliances.

Adding Major Appliances/Devices

Before installing major new appliances like hot tubs, EV chargers, tankless water heaters, or HVAC systems, the existing electrical panel and wiring must be assessed. Most homes lack sufficient spare electrical capacity to support major additional appliances without upgrades.

If a new appliance exceeds the current panel rating or circuit capacities, overloads and blackouts become inevitable. Consult an electrician early in the planning process for any high-wattage appliance installations. Pre-installation upgrades prevent wasted money and headaches down the road.

Expanding a Business

If your business is undergoing expansion by adding more equipment, workspaces, or computing needs, expanded electrical capacity will be required. Simply plugging more devices into existing outlets risks overload failures. Having an electrician handle wiring major business expansions ensures adequate power to all new areas per code. They specify appropriate wiring gauges, circuit sizing, added subpanels and new outlets placed expertly. Attempting business expansions unthinkingly without assessing electrical impacts leads to frustrating losses in productivity from sporadic power interruptions.

Safety Upgrades for Aging Owners

As homeowners age, living spaces should be adapted to support limited mobility and healthcare needs. Key safety upgrades electricians can provide include:

Installing occupancy sensor lighting for navigation.
Adding electrical outlets at bedsides for medical devices.
Increasing lighting brightness.
Wiring for emergency response systems.

These seemingly small enhancements allow peaceful ageing in place rather than costly relocation due to electrically-equipped homes. Electricians help tailor electrical environments specifically for unique health situations.

Key Factors In Switchgear Selection

When looking to install new switchgear or replace outdated gear, several factors influence which solution best fits your electrical system needs:

Available fault current levels – The maximum available short circuit current must align with switchgear interrupting ratings to allow safe fault clearance.
Voltage class – Match gear voltage insulation ratings to your utilization voltage ( 480V, 600V, etc).
Physical dimensions – The switchgear enclosure footprint must suit designated installation spaces.
Electrical expansion provisions – Scale amperages and space for additional future circuits.
Compliance with safety/performance standards – Ensure switchgear adheres to all required electrical codes.
Desired special features/capabilities – Select gear offering applicable ratings like arc-flash reduction, tiered redundancy, etc.

Consult qualified electricians to learn more about switchgear specifications for your system to determine optimal capabilities. Proper initial gear selection prevents costly future upgrades or failures resulting from under-rated equipment. Understanding the capabilities of various switchgear components assists greatly in planning critical system expansions and upgrades.

Regular Electrical Inspections Are Vital

Alongside watching for the above trouble signs and emergency issues, arranging routine electrical inspections drastically improves safety. Having an electrician annually assess all wiring conditions, connections, and electrical panels identifies deficiencies before catastrophic failures.

Thermal imaging scans can uncover hot spots in Questionable wiring that may otherwise go unnoticed for years until causing a fire. Given the sheer scale of wires embedded throughout buildings, even careful visual examinations can miss slowly degrading insulation or terminals. The technology-assisted preventative inspection provides total visibility of all internal electrical stability.

During major building milestones like remodels, occupancy changes, or significant appliance upgrades, thorough electrical re-inspections also provide value.

Prioritizing ongoing electrical maintenance ensures your most vital household systems remain fully functional, efficient and safe from breakdown over decades of continual operation.
