No, it's not ok. For one thing, by the time the city inspector looks at the fully framed building, it will be a little too late to fix it. Secondly, the builder's attitude seems very questionable. Either his framing crew or the concrete sub messed up. At the very least their job is not done in a workmanlike manner. They shouldn't wait and hope things 'slip' ...

I was curious so I just did some googling around and it seems that, if anything, some lenders might require a closet for a room to be included in the bedroom count for the house. I imagine this might be to help ensure consistency in home valuations. Check the first few results here for more info. Code does require a bedroom have an egress window however. ...

Yes, you can use larger wire. However if you are putting in a junction box it must remain accessible. That means you cannot cover it with drywall or hide it behind anything.

Looking in 2011 National Electric Code Changes of Interest, they reference NFPA 90A-2009 : Section 4.3.4 of NFPA 90A-2009 states that “Wiring shall not be installed in air ducts” unless it is “directly associated with the air distribution system and does not exceed 1.22m (4 ft).” I don't have access to the full code, but just in the notes on the ...

I don't like it since it risks potential confusion in the future as to whether the circuit could be upgraded to 30amps, but if you're going to do it, use the 10g wire at the end of the run and not at the breaker panel where the mistake would be easier to make.

Double Taps With most devices you can only have one wire per screw terminal, however, some breakers do support multiple wires under terminals. If the device allows multiple taps, it must be listed for the purpose. NEC 2008 110.14 Electrical Connections. (A) Terminals. Connection of conductors to terminal parts shall ensure a thoroughly good ...

I couldn't find a solid source that says a closet is Required, to make a room a bedroom. It seems to depend more on the agency listing the property, and the mortgage company financing the sale of said property. The only requirement I could find dealing with bedrooms from the Federal Housing Administration (FHA), was that an emergency exit is required. ...

This wil depend on where exactly you live. There're many possible outcomes, including the following: nothing bad happens you can be fined the house can be demolished and you'll have to pay for that you'll be forced to go through the "proper channels" later you'll face minor or major problems when you try to sell/lease/insure the house Also don't forget ...

Per the wording of that code, you can't be adding anything to the floor or the ceiling as you'll be under the 7' minimum. You could consider a super-thin flooring (stain the concrete? Linoleum?) and then, as you suggest, put the sheetrock between the joists (though that sounds like a finishing nightmare). Alternatively, raise the foundation (likely cost ...

A sub panel must have the neutral and ground isolated. Panels come with a very long, rather thick (about 1/4 x 20) green bonding screw that connects the neutral bar to the can in the case of a primary panel. You don't get a neutral from your utility, you create one with that bonding screw. Sub panels should be fed with 3 insulated conductors of appropriate ...

If the #14 or #12 wire is a branch going to specific loads, then it is "safe" with respect to that load. It won't overload that wiring regardless of the breaker capacity use (or even if the breaker is bypassed entirely). However, this is unsafe in the context of changes in usage. The electrical code focuses on safety and rightly prohibits this. The ...

Overcurrent protection devices must be Readily Accessible. The NEC defines Accessible as... Accessible (as applied to equipment). Admitting close approach; not guarded by locked doors, elevation, or other effective means Accessible (as applied to wiring methods). Capable of being removed or exposed without damaging the building structure or finish or ...

OK this is easy. The answer is NO. The construction has issues: There are no bolts for the sill plates. 2.The sill plates should be spaced on the slab so that wall plus exterior finish meets slab. It looks like this house is getting brick or thick stone given the 3 inches or so from the edge. I am not sure about your situation. You are having a ...

If you are going in-wall over 16 feet, you need an active extender as many have pointed out. One alternative to this is to use a Cat5 extender: this allows you to run Cat5e/6 in-wall (riser or plenum cable is rated for in-wall use), then convert to USB at both ends as needed. One I found at Monoprice is rated for 150ft.

I will not speak to the code issue as other already have. But, I did use them when building my new home a few years ago and, for me, they passed inspection. While the package does say they can be used for stranded wire, I did not find that they worked that easily with stranded wire (I was using some computer controlled switches with pigtails instead of ...

There should only be one wire per screw terminal. One of my wiring books says that some local codes allow splices inside a service panel, and some don't, so you should check with your local authority to make sure it's OK in your area. However, regular circuit breakers are only a few dollars, so even if it's allowed in your area, my advice would be to ...

Yes: NEC 2011 334.30(B): Unsupported cables. Nonmetallic-sheathed cable shall be permitted to be unsupported where the cable: (1) Is fished between access points through concealed spaces in finished buildings or structures and supporting is impracticable. (2) Is not more than 1.4 m (4½ ft) from the last point of cable support to the point of ...

Their insurance may lean that way. Rates are probably lower if they are not selling to end-users. They may also not have to deal with sales tax, if they are not selling to end-users. As for the (or more) economic incentive many take for granted: the cost of customer service. The below consumes valuable man-hours and to staff this could double payroll: They ...

Nonmetallic-Sheathed Cable The Answer According to the National Electrical Code, you can have 4 12/2 nonmetallic sheathed cables through a single bored hole that is fire- or draft-stopped using thermal insulation, caulk, or sealing foam, or where proper spacing is not maintained for more that 24 in. If you maintain proper cable spacing (which is defined by ...

According to the National Electrical code, you have a few options. Depending on the situation, there are a few code sections to pay attention to.

I'm not sure i fully understand exactly what you intend to do from the sub-panel in the garage, but I think I understand that you want to parallel off the existing input lugs of the 50 amp breaker to an additional panel. If this is the case, what you are contemplating is called double tapping and is forbidden. You may not connect two wires to any hot lug in ...

If your wall is closed up then you don't have to worry about it. It looks like class 2 wire is rated to go into walls. Only use wire that is rated to be in the walls for uses like what you have. The only things to worry about with class 2 or class 3 wiring is: Class 2/3 should never be used in the same electrical box (without a low voltage divider or in ...

The OP has a great reason for using 12 ga. wire. He already has some on hand, so using it is cheaper than going to get new 14 ga. wire. It's perfectly safe to use it. Don't worry about confusing future workers. If they want to add something to the circuit, they will have to go turn off the circuit breaker first, and then they will see they are working ...

The meters shouldn't interfere with each other. They're just ammeters, after all; current is current. You will be charged for the parasitic load your new meter introduces, of course, which may vex your test. Bigger problem is that you'll need the electric company's cooperation to turn off your circuit so you can rewire—and they are almost certainly ...

Around here, 4x4s are not uncommon. This table shows that a 4x4 pine post that is 6 ft or shorter can support a load area of up to 10 ft² assuming 50 lbs/ft². Don't trust me or a random table on the internet; make our own calculations from tables in the building code or other trusted sources and consider having them checked by an engineer.

As longneck said, the utility easement is for use by the utility companies only, and you would be unlikely to get regulatory blessing from the TUC (Texas Utility Commission) or local service providers. You MAY be able to convince your neighbors to allow a new easement. However, this may also be unlikely, for a couple of reasons: Easements are generally ...

Generally, no. The utility easements are for use by utility companies, not individual homeowners. If you tried to ask for official blessing, you wouldn't get it as you are not a recognized utility.

You're mucking around with 125V subpanels, which I don't know enough about to comment on. However, here are two other options: You may be able to replace existing full-size breakers with duplex breakers. The limits on the number of breakers may be printed on the panel somewhere, or you can check with the manufacturer. You can also replace the existing ...
