I'm opting to swap out my doorbell system with a wireless one. These wires look to be connecting to the doorbell system for power. Can I just unscrew these and electrical tape or wire nut them off separately? [ATTACH]52337[/ATTACH] For the wires at the door, should I just use electrical tape and put them back into the door frame? Is there any need to worry about turning off the power to these via the circuit box, or are they so low voltage that it won't matter. Thanks for the help. Any other tips or tricks would be great.

First post so bear with me here. First will be a description of what I have going on followed by a few questions. Planning to wire a small 60a sub panel in my detached shed/garage. Panels will be located approx. 100 cable feet apart. In my shed I do not plan on running any large tools or equipment. Panel is for lights and receptacles. I currently have 2" pvc conduit run 18" underground with two 90 degree "stub ups" (one behind the shed and one outside the house opposite the main panel) Stock photo of subpanel for reference: [ATTACH=CONFIG]52307[/ATTACH] [url=http://www.lowes.com/pd_12561-1318-E0816ML1125S_1z0uy04Z1z0v8owZ1z140f2__?productId=3127663&pl=1]Shop Siemens 16-Circuit 8-Space 125 Amp Main Lug Load Center at Lowes.com[/url] Questions: - 60a 2pole breaker at the main panel. The panel shown above has no "Main" breaker. Would backfeeding a main (60a 2pole) breaker per the manufacturers instructions or a separate 60a disconnect/enclosure feeding the buses be preferred? Since I do not need more than 6 circuits backfeeding would not be a spacial issue. - Cabling: #6/3 romex would be allowed while inside either structure (home and garage) but would not be allowed in the buried conduit correct?

Black 6-3 Romex NM-B W/G Wire-63950002 - The Home Depot[/url] I am under the impression from researching that NEC views the outdoor PVC as a wet condition and that I will need (4) #6 THWN cables instead or a #6/3 UF cable. Ideally running the #6/3 NM-B the entire length would be easiest though. - Would a LB fitting be best to penetrate into the home? My plan for the garage end is to use an LB and penetrate under the panel near the floor level. If #6/3 romex is not allowed per NEC would I need to use the romex from: [Main panel -> LB penetration] then splice to #6 THWN for the length to the next LB? The same would go for the other end as well. So it would look like this- Main Panel---[#6/3]---LB*Splice*---[(4)#6 THWN]---LB*Slice*---[#6/3]---Subpanel - I know I will need to drive a dedicated ground rod for the sub panel but will I need to install a floating neutral bus? The sub panel currently only has 1 neutral/ground bus. - I noticed the other day my duct tape caps that I used are starting to deteriorate. What would be the easiest way to remove any water buildup in the conduit? I haven't checked how much is in there and I don't know how long the duct tape has had openings. My current plan is to break out the shopvac unless someone has a better idea. Then I'll reseal them a little better this time. Sorry for the lack of knowledge and numerous questions. I have done plenty of electrical work around the house and on job sites (when I was younger) but I have never tackled this specific job before especially on my own home. I want to make sure that I get this right the first time without any complications. I can also provide pictures if needed. Thank you in advance!
