In the age of YouTube tutorials and DIY home fixes, it’s tempting to try and repair that flickering light, replace a socket, or fix a tripping switchboard yourself. But when it comes to electrical work, even the smallest misstep can lead to serious hazards—from electric shocks to house fires. For homeowners in Kochi, where humidity, salt-laden air, and aging wiring are common, the risks are even higher. At Oh Yes Services, we’ve seen how well-meaning DIY attempts have turned into costly, even life-threatening, emergencies. Here’s a breakdown of the DIY electrical repairs you should never attempt, why they’re
dangerous, and when to call a licensed professional.
1.Replacing or Repairing Switchboards
Why It’s Risky:
● Even with the main switch off, residual current can remain.
● Poor handling can damage internal wiring or lead to short circuits.
● New-age MCBs (Miniature Circuit Breakers) require proper load calibration.
Real Risk in Kochi:
Moisture in the air increases conductivity. A misconnection in a switchboard could spark electrical fires, especially in older buildings.
Professional Tip: Only a licensed electrician can assess the load distribution and earthing safety before making replacements.
2.Fixing Exposed or Burnt Wires
Why It’s Risky:
● Simply taping or twisting wires together doesn’t ensure insulation or long-term safety.
● You may not detect deeper damage, such as a partial melt inside the wall.
Real Risk in Kochi:
In humid climates like Kochi, poor insulation degrades faster. Improvised fixes can become fire hazards within weeks.
3.Installing New Electrical Appliances Without Load Check
Common DIY Mistake:
Plugging in a high-wattage appliance (like a heater or oven) into an old socket without checking circuit capacity.
Why It’s Risky:
● Risk of tripping breakers or overloading circuits.
● Possible fuse melt or wire burn inside the walls.
What You Should Do:
Always get a load assessment before installing heavy-duty appliances.
4.Changing Light Fixtures or Ceiling Fans
Why It’s Risky:
● Ceilings often hide multiple live wires.
● One wrong connection can short your entire lighting circuit.
● Improper installations often come loose, posing fall risks.
Professional Tip:
Electricians use voltage testers and anchoring tools to ensure ceiling safety and correct polarity wiring.
5.Rewiring or Extending Power Lines
Why It’s Risky:
● Involves accurate load balancing, voltage drop calculation, and gauge selection.
● Mistakes may not show immediately, but will surface as flickering lights, MCB trips, or shock risk later.
What Makes This Worse in Kochi:
Old houses with concealed wiring make it nearly impossible to trace circuit continuity without professional tools.
6.Installing or Replacing Earthing Systems
Why It’s Risky:
Earthing isn’t a visible component—it’s your home’s hidden safety net. Poor earthing leads
to:
● Live current leaks in metal surfaces
● Risk of electrocution during rains or while using wet appliances
● Burnout of sensitive devices
Warning: Improper DIY earthing can be deadly in monsoon-heavy Kochi.
7.Using Generic Extension Boxes to Power High-Wattage Devices
Why It’s Risky:
Most extension boxes are not designed to handle geysers, irons, or microwave ovens. They:
● Melt under load
● Can cause plug-point fires
● Lead to overheating wires behind walls
Safer Option:
Have an electrician install a dedicated high-load socket with surge protection.
Why Electrical DIY Is More Dangerous in Kochi
Kochi’s coastal climate adds extra strain to every electrical system:
● Humidity weakens insulation
● Salt air corrodes terminals
● Monsoon leaks expose walls to dampness, increasing risk of arcing
Even if you’re confident in your fix, these hidden factors make professional inspection
essential.
When Should You Call an Electrician?
You should never hesitate to call a professional if:
● A plug point or switch feels hot or smells burnt
● You experience frequent power fluctuations
● A circuit trips repeatedly
● You’re installing new appliances
● You’re unsure whether something is properly grounded
