Installation

Previous Question

Can replacing a meter cause power surges that can damage electrical devices? If so, who is responsible?

Next Question

Taking out or putting in a meter does not cause a power surge. The power is cut only briefly so the meter can be replaced safely. It’s a simple operation, equivalent to switching a light on or off, for instance.

However, in two rare circumstances independent of Hydro-Québec activities, damage may occur: if there is a problem with the customer’s electrical installation or if the damaged electrical devices are more sensitive or are already susceptible at the time the meter is replaced.

In November 2013, the Corporation des maîtres électriciens du Québec issued a reminder of the importance of inspecting the socket regularly (in French).
