Switch

I am making a BOSOZ. For the power switch.. is it OK just to open one leg of the 120v or is it best to open both?

kennethrl,

>> OK just to open one leg of the 120v

If you use a single power switch -> check to cut the hot wire...

with a double power switch, you'll get no more advantages.

Regards.

Best practice is to switch both live and neutral.

I usually do but I don't know why.

Why?

Sometimes the power socket in the wall is wired backwards (neutral and hot switched). If someone is using a cheater to convert a 3 prongd plug to a 2 pronged plug, it can be inserted upside down and thus switch the hot and neutral.

Ah hah! The backfeed from a neutral.

That's why I'm a sissy and always disconnect the mains before working on the 110V stuff.
