" When this house was built in 1897 it was illuminated with gas. Probably in the 1920s they improved the technology up -- knob and tube electrical wiring. Since then -- in the forties and the fifties they outdated and as of last year we have a brand new 200 -- service and then a hodgepodge of different types who works we've gotten rid of all of that. Barry Driscoll is totally rewiring the -- bond with a few numbers. And how I guess this is the feed to the third floors that yesterday's. This whole thing that third plus something at all. Which also feeds public -- handlers. Couple bedrooms and bathrooms and a bigger that's him that's right this is basically the third floor teenage area the living room where you could have party if you could have. A lot that's right -- a lot of noise -- that that has to go all the way to the basement right yes it does and it ties in to the news service yes. And then we've got favorite thing that. OK we have more similar -- same title without wires it okay that's that this is a 33 sub feeder. Which is going all the way back up. From downstairs to the second floor -- a just like the third row of -- where. So if anything goes wrong on the third floor you go to the sub panel up there to check out circuit breaker that same thing happens here that's right and we're standing in a utility closet on the second floor where we're gonna. Install a stacked washer dryer for immediate family kind of stuff and we're also gonna have storage and an linen closet function here. But it serves the purpose of having the panel located accessible but not out in plain sight in the middle of the hallway. Fit so what are the three yes there's the red to black or red on black -- hut conductors the white is on neutral connect the white has been neutral and that they are. Copper is agra -- realty. All the -- code before we defeated the groove into the panel. That's right throughout Romex connector -- into the panel. -- that have a lot of juice that's coming through here now how how do you secure this in the box. -- could secure it actually two of the Romex connector which makes it grout itself through the to the camp which the -- located -- OK we have our grounding conductor which unit is going to go to the ground -- neutral which goes to the neutral but you and I are too hot links from right in on that. On the two largest OK and then all the individual. -- circuits here are labeled here. And you see with Clinton and stealing -- like -- U haul lights -- through everything will be identified. -- issue but although this you know to it to us. Just looks like we're pulling a lot of wires into places that are this and one of the most dangerous jobs that anybody can undertake in a house. And I always discouraged to Richards offers from getting involved in. This type of work. And bringing a professional and of course the professional staff to answer to the inspector. Right now we should be able to find. City of Cambridge electrical inspector up on the third floor. And that's that's. The service like Bob so little servicemen and comes to work in this unit in sunlight with NAFTA. Now is that just an added good anytime assurance epithets -- require all that's required by code along with the convenience outlets for servicing unit. For servicing the air handler that we were looking and talking about earlier in that's a very very good idea now I know we've got a sub panel in here in this storage closet. And I know that you're expecting just the third floor today right yes now what what sort of stuff -- you looking forward when you well inspection."

" The sub panelists one thing that we're looking at Bob making sure that we have enough power coming up here. And the fact of its location now I did notice you said that this was eight. -- And they've accomplished that they've done a very nice job he now does the city of Cambridge or the state of Massachusetts a lot. Homeowners to do their own wiring and it in their own remodeling projects. Well I'm told the state law requires that you be a licensed electrician and you go to a -- courts and you gotta have a license and that's -- benefactor as I understand it -- one of of the of the leading causes of house -- and fatalities is. Electrical wiring problem precht correct. Especially in an -- of wooden frame building -- would find it a lot of people have done that themselves anymore and that's cost from it is a difficult situation. Anything unusual about what we're doing up here issues in the you know we're creating a big kind of family room up here. Well basically everything ceased to be in pretty good shape because your outlets. Well -- called required to be twelve feet of hot glue it and not standing at any point. More than six feet from an outlet from an outlet and that's to reduce the number of extension cords that people you're right exactly and now they've done a very good job of securing all the whining here -- And it appears like. In using I would say half inch rock yeah as a way though the boxes out away from the stud about a half inch that's right. And our lighting and here's a little bit unusual. Yes what we're doing on the tops of all these beings that strip halogen lighting with a can be applied to general lighting. And then if you need to light a specific thing like pool tables or card table they'll be. Track lighting which you can focus."

In this segment Bob meets Eddie Fisher, the master electrician on the Brooklyn project's infrastructure team. The team of five electricians from AC/DC Electric is rewiring the building from basement to roof deck. Fisher's team is pre-wiring the building for telephones, computer and cable TV. New York City building codes often require the use of materials and techniques not often seen in residential construction. Codes enacted in the summer of 2003 in New York City require a separate power line from the main electrical box to each GFI (Ground Fault Interrupt) circuit. Also required by code in this building is the use of BX, or metal-shielded, cable. BX is a rigid, flexible metal conduit with a wire bundle, consisting of individually insulated conductors covered by a flexible spiral-wound layer of metal. BX will typically last longer than vinyl-clad cable and may prevent some inadvertent damage in the future.

low voltage vs line voltage halogen lighting

I like the idea of low voltage recesssed halogen lights but my local hardware superstore stocks mostly line voltage fixtures. Are the low voltage fixtures unpopular for some reason?

low voltage vs line voltage halogen lighting

No, in fact I prefer the low voltage tracks. The difference is aesthetics. With line voltage systems you must use a 110V bulb which I think comes in only 1 size or you must use transformers at each lamp fixture on the track, this makes them bulky.

Halogen lighting

I am trying to decide whether to purchase halogen light fixtures for the bathroom or stick with conventional incandescent fixtures. I understand that most halogen fixtures require a 110-12V transformer to be installed, either hardwired or attached to the electrical box.

Halogen lighting

I have many low voltage transformers where I work and three 120 volt halogen ceiling lights.Transformers are safe and usually have a decent life to them.The halogen fixtures however get hot enough to cause concern.
