3. Inspections of Commercial Electrical Systems

  • Focus: The electrical systems of commercial buildings, such as offices, shops, and restaurants, are the subject of these examinations.
  • The Inspector Searches for Inspectors to check for compliance with fire safety rules, confirm correct wiring for commercial lighting systems, test emergency generators and backup power systems, and guarantee sufficient capacity for high-power equipment.

4. Inspections of Arc Fault Circuit Interrupters (AFCIs)

  • Focus: The purpose of these inspections is to evaluate the performance of AFCI circuit breakers, which are sophisticated breakers intended to identify and stop electrical sparks that have the potential to start fires.
  • What the Examiner Searches for: Using specialized instruments to mimic arc faults, the inspector examines AFCI breakers and confirms they trip appropriately to avert possible fires.

Signs That Indicate the Need for a House Electrical Inspection

To guarantee the security and efficiency of your electrical system, there are a number of warning indications that point to the necessity of a home electrical inspection. In fact, this checklist is a home electrical safety check.

Here are a few crucial ones to be aware of:

Problems with Lighting

Lights that flicker or dim might indicate a breaker that is malfunctioning, weak wiring, or overloaded circuits.

It's a good idea to contact an electrician if your lights constantly flicker or dim, especially when you turn on appliances.

Burning odors near light switches or outlets is a major warning sign that may point to electrical arcing or overheated wires, both of which can be fire hazards.

Issues with outlets and switches

When you plug in or turn on appliances and notice sparks emanating from the outlets or switches, this is a warning indication and has to be attended to right away by a licensed electrician.

To the touch, electrical switches and outlets shouldn't ever feel warm. If switches or outlets feel hot to the touch, there may be a fire hazard due to overloaded circuits or unsecured wiring.

An electrician must fix any outlets or switches that feel loose in their sockets when you put anything in or turn them on. This poses a safety risk. Arcing and overheating can result from loose connections.

Older homes often have two-prong plugs without grounding prongs. These outlets should be replaced by a licensed electrician with three-pronged grounded outlets as they don't adhere to modern safety regulations.

Additional red flags:

  • Visible Damage to Electrical Components: It's critical to contact an electrician for an examination and repairs if you see any visible damage to your electrical panel, outlets, switches, or cables (such as cracks, scorch marks, or exposed wiring).
  • When you touch an appliance and get a tingling sensation, there may be a risk of electrical shock.
  • Unexplained Burning Odors: Although the burning smell may not be emanating from an electrical component specifically, it may be an indication of electrical problems leading to overheating in appliances or walls.
