Emergency Electrical in Ottawa, ON

A deeper look at how Ottawa conditions shape the emergency electrical work owners actually need.

Ottawa's 10 year old and older housing stock creates electrical emergencies that require an electrician who can work safely in systems that combine multiple generations of wiring. A 1930s Glebe home may have original knob and tube feeding the original circuits, aluminum wiring added in a 1970s renovation on the upper floor circuits, and modern copper romex on circuits added in a 2010 kitchen renovation. Diagnosing a fault or power loss in that building requires understanding all three systems and their interactions. An arcing fault in the aluminum wiring section of an Ottawa home can cause a fire if it is not isolated immediately. Aluminum wiring oxidizes at connections over time, increasing resistance at the connection point, which produces heat, which accelerates oxidation, in a cycle that eventually causes arcing and fire risk. The ESA licensed response to a suspected aluminum wiring arc is to isolate the circuit at the panel, inspect all accessible connections on that circuit, and either install aluminum rated connectors or repipe the affected circuit with copper. In an emergency context, isolation happens first, assessment and repair follow.

Ottawa's older apartment buildings in Vanier and Lowertown present a specific emergency electrical scenario: the building may have a federal Pacific or Zinsco panel that was installed in the 1960s or 1970s and has known breaker failure patterns. A breaker that has welded closed in a Zinsco panel is an emergency condition because the circuit is now unprotected against overcurrent. Our emergency electricians recognize these panel types and can isolate the affected circuit safely while the property owner evaluates a panel replacement, which is the appropriate long term resolution. ESA required documentation is generated for every after hours job where a permit is required. All emergency work is photographed. Call 1-855-910-9090.
