Cavity floorbox in a solid floor

[Gaz the Sparky]

Sounds like a good idea to me. I have installed floor boxes in a concrete floors before it was a messy job. I used an angle grinder to cut the hole. I would install a couple of tubes for future use though.

I'm currently emptying the garage before I get the sthil saw out. Even with a hose attatched, its going to make a horrible mess

Suprising what you find. Anyone need some glands for 4L2.5 pyro?

Sounds good to me. A flex from the ceiling would always be getting in the way.

By the way, Rocky, under what conditions can strobing occur? Is it when the rotational speed of a machine exactly matches the 50kHz supply of a fluorescent fitting? I only use fluorescent lighting in my workshops, and I've never seen a moving blade looking stationary.

Don't know exactly,maybe as Jonn D says.
we was taught it at college before HF lighting was out.

When I was an apprentice they seemed to only use twin switch/start fittings.

For One side of the fitting, inside it had a capacitor in series with the choke unit.
Causing the two tubes to be out of phase with each other.

Not sure if they are still made now.
I would suppose they would have only been safer if both tubes work in the first place.
