Can 90C UF-B 8 gauge wire support a 50 amp circuit under the National Electrical Code?

I see conflicting data online as to whether the amperage limit is 40 or 55 for this type of wire.

What size and type of wire is recommended for new wiring from a meter to the electrical panel / breaker box?

electric — Mon, 06 Feb 2012 21:52:39 +0000

I am wiring my newly built garage and have to put it all the circuits and outlets and lights. I also have a garage heater to wire in at 240V and 30 amps. I have a breaker panel rated at 125 amps, and need to connect the meter, which is outside on a pole located 90 feet away. I plan on running that entrance wire underground to the garage from that pole, so am unsure on what size and type of wire is approved for that purpose. Any other tips and advice would be valuable to me.
I have had sales people tell me 10-3ub-f and 8-3ub-f,..and yet another sales person who says those are not big enough to power my service adequately. HELP!
The meter is already installed and mounted on a pole nearby, wired and ready for me to connect to my panel. Ground wire and ground rod will be done at the same time panel is installed. The utility company tells me that once I connect to the meter pull the breaker switch on the meter and I will have power. I need the wire size and type (rated for 100 amps.) to proceed with my preparations to do the job myself,..permit is in hand.

How do you secure NM wire near electric box in a wall with existing drywall?

electric — Tue, 24 Jan 2012 19:02:25 +0000

Electric codes require NM wire to be secured within 12″ or 8″ of an electric box, which is easy enough in new construction, but how do electricians secure NM wire when remodeling with new boxes in walls with existing drywall? Is there a special tool or an exception in this circumstance, or is it expected that a larger area of drywall will be cut out for this purpose?

What type of wire do PC cases use? the wiring used by computer power/reset push buttons?

electric — Mon, 02 Jan 2012 11:56:35 +0000

i’m having a hard time looking for them since all the computer/electrical shops that i’ve visited don’t sell that particular type of wire.

i learned from electrical shops that wires have actual technical terms. like 16 gauge wire etc.

the ones used by PCs are not the same type of wires used by radio. the wires are smaller.

the one that came with the case is too short, i want to reposition the button on the top of the case for easier access

How to connect a wire to my amp in my car without getting shocked?

I just need to connect a wire that got pulled out to my amp. i had my car completely turned off so i went to connect it and it barely touched another wire and it sparked. i thought this wouldnt happen if my car was off. so my question is how can i safely connect the wire without getting shocked. or how would i turn off all of the power so i dont get shocked?
how would i disconnect the battery or fuse? do i need to do this or can i somehow connect the wire without turning anything off

Electrical Problem – exposed live wire inside the circuit box!?

electric — Fri, 09 Dec 2011 09:20:34 +0000

This is what my home inspection says about this problem
“Wiring to dryer 240 V circuit has been reconfigured in a sub-standard manner. The 240 V circuit has been split but one live wire remains in panel improperly terminated. Wire to second leg of 240 V dryer circuit is undersized.”

Anyone know how much this will cost? I’m assuming I’ll need a certified electrician.
