If there is no indication whatsoever then no, it doesn’t matter. That looks like an internationally universal ballast, so in the US you’d have two hots @ 240V/60Hz, and in a place like the UK you’d have a hot and a neutral @ 230V/50Hz.

Does it matter which way live and neutral?

The answer is fairly clear. Yes it matters, because it reduces the possibility of an appliance/device becoming a shock hazard.

What happens if a ballast is wired wrong?





The ballast is wired to the home’s hot, neutral and ground wires on one end, and to the light fixture’s lamp holders on the other end. If a ballast fails, it can cause a short, burn out tubes or even cause a fire, so it must be replaced.

What happens if live and neutral are reversed?

If your outlet’s polarity is reversed, it means that the neutral wire is connected to where the hot wire is supposed to be. This may not sound like a terrible thing, but it is. There is always electricity flowing out of an outlet with reversed polarity, even if an appliance is supposed to be off. Why is it dangerous?

Quote from Youtube video: For two parallel fluorescent tubes. We will duplicate the ballast. And the shorter connect the line source to one pin of the switch. The other pen will be connected to one pin of each ballast.

Does ballast have polarity?

If the lamp is fluroescent, it has a ballast. If you can get to that, the ballast should be marked with either the polarity or the usual black and white wires for hot and neutral. Polarity should not matter though, with AC power.

What do I do with the yellow wires on a ballast?

The common yellow wires connect from the ballast to push-in connectors on one of the right holders of lamp 1 or 2. Two yellow wires connect the common lampholders together.

Remove the wire nut from one of the power wires and carefully strip about 1/2 inch of insulation from the end, making sure not to touch the end. Hold the ballast wire next to this wire with the stripped ends parallel but not touching. Quickly slip on the wire nut and screw onto the ends.

How do I stop my fluorescent lights from flickering?

Brush dust out of sockets, then reseat firmly. If the tube still blinks when the light is turned on, wiggle it a few times while the light is on to see if this cures the problem. If not, take the tube out and inspect sockets closely to see if spring contacts are bent or corroded.
