Hi All, Hopefully this is the right place to post this question. I purchased a very simple USB LED light circuit with a capacitive touch switch. You basically plug it into any USB socket that has power and use the capacitive switch to turn on the one LED. Here is a link to the product page: [url]https://www.amazon.com/gp/product/B00QVR6K4Q/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1[/url] My question is if I could buy off the shelf button batteries or maybe even a MN21/23 type batter to run this as a stand alone device without USB power. I'm 3D printing a housing for it to mount for a specific purpose and I don't have USB power available. The complication is that space is tight, so I just can't use a USB power bank. The details on the LED light are sparse, but I assume it falls within the limits of USB 1.0 at minimum (100mA / 5V / 0.50W). As you might be able to tell, I have almost no background in electrical engineering, so this might be a very simple question.

Hi. I want to install a sub panel in my workshop and feed it from the main panel. I bought an [B]Eaton BR indoor main lug[/B] panel that can accommodate 8 circuits which will be perfect for my needs. Upon inspection I noticed that the panel has only 1 bus bar in it, and I was expecting 2. One for grounds and one for neutrals. Did I get the wrong type of box? If NO, how would this guy wire up, I'm assuming the bar is for neutral... John
