Ballast wiring???

[i=p/u]

If you wire a ballast incorrectly , would it damage it?

I got a 2x 42w ballast today and the numbers are different on this one.

What does the wee star indicate on the Ballast wiring diagram?

Any help need more info just ask thx.

why do they need to be short as possible?????


a guy i work with told me it doesnt matter as long as you match the browns from one lamp with the blues and yes the astrix means the shortest ... so not loads init and its up and working and everyone is happy. ty

I have no idea, other than the instructions say so.

1,2 has the we star which was neutrals
3,4 was line's
5,6 was neutrals
7,8 was line's with the wee star
Hmmmmm

And the new ballast has 10,11,12,13,14,15,16,17 with wee stars between 10,11 and 16,17

Hmmm I'm probably over looking this but the ballast cost £80

80 quid for a ballast that must be a typo right?
