Hi,

I would like to install a ceiling fan in my bedroom. The existing electrical box does not appear to be approved for supporting a ceiling fan, and this electrical box is completely embedded in the concrete ceiling.

I wonder what options I have to install this fan. Could I order a custom-made circular steel plate with four mounting points and a hole in the center to access the wires from the junction box behind it?

What other options am I left with while respecting Quebec electrical rules?

Installing a ceiling fan when your existing box isn't fan-rated and is embedded in concrete is definitely a challenge, but there are workable solutions. The key issue is that a ceiling fan requires a box rated to support dynamic (moving) loads — typically 35 lbs static and 35 lbs dynamic — which standard junction boxes are not designed for.

Before diving into options, one important note: you mentioned Quebec electrical rules. My expertise is specifically in Ontario's electrical regulations (the
