Why do I have to supply you with a 1" EMT for two cat. 5's?

Just kidding.:grin:

A buddy of mine is looking for type LMR 400 cable. I don't see this in the NEC. I know the M is medium power and the R is riser. Whats the L for and where would get this?

It's for an antenna for wireless internet.

Thank you.
 
Thanks guys, did the google.

I just looked in the 08 and there no mention of LMR. Theres BMR as in the 05.

Would this fall under CATVR?

Because these are the people who used to work for the phone company and would want a 4" conduit run from the tel-closet to the street for a 25-pair cable. :grin:

With no more than 180 degrees of bend, and a 4' x 4' x 6' "pullbox" (coffin) with hinged cover if there is.

Interestingly, we used to coil fiber optic cable into slack coils in manholes - 80-200' of it into a circle with a 30" diameter... (Looks like a garden hose on a reel) fed through 1& 1/4 innerducts, but send that cable into a building and suddenly the requirements are no less than a 4" pipe with bend radius no less than 10' using segmented, multi-shot bends...

When I am king, I'm gonna change a lot of rules...
 
LMR 400 is flexible coax jumper cable, I have installed hundreds of feet of it.
Its made by times microwave and I get mine from Tessco.
LMR 400 FR is the type used inside a building.
 
i need to get a pic on here of a house i was at last night. the phone company grounded to a hose bib, which is connected to PEX. i was there to meet the satellite installer who couldn't figure out what a media panel was, and just ran new coax on the oustide of the house and drilled holes through the walls. guy told the HO it was his first day, and took him 8 hrs to connect two tv's. tried to use a splitter installed for an antenna to run his directv. just blew his mind that it wouldn't work.
 
1" Cat 5's SOP

1" Cat 5's SOP

The Local universites are all in love with 1" EMT for telephone work, its just SOP and they also spec 4-11/16 boxs

He's a job, I'll be on for quite a few more months, I didn't do any of the work that follows:

This is a small lecture hall, note the light is for the steps of a stair stepped lecture, which was an engineered mix-up, there is no way to hard pipe to this device.

This is in the individual offices of the Grad students, typical. I have no clue(just never asked) what the 6x6 box is.
HPIM0537.jpg

This was an exterior wall, a continual window runs across the first floor, again its a Grad's Office. On the right side of picture, not the angled worked. This room happened to need reworking, the orginal work was
all angled up and out semitric to itself cause of the Telephone 180? rule.
I didn't ask what happened here! ? :)
Gezz, I'll have to hit them up next week on the straping on the Left, Duh.
HPIM0538.jpg

West side, note grad offices on 1st floor and continual window. See the white Grills on the end of building
That my 10-20.

In that first picture - THATS NOT MC CABLE IN THE WALL?!?! WHAT!!!! On a project funded by the state of North Carolina. It must be a private university. The 2 projects I have picked up from the state Mc cable is to be used for flex whips to light fixtures only. of course not to exceed 6'

When owner /occupants start getting to involved with these projects at a lot of "higher level of learning" institutions you can have a tragic mess!! To say the least!
 
Nice Light, Bad App

Nice Light, Bad App

It was all covered by an RFI! The light is a dimmable florescent, while a very nice light its notched in a 45? on the corners, with a 1/2" knock out implied. This notch to notch on both side is where the dimmable ballast sits and takes up the whole space. Thus no back entry, or top or bottom.

The other headache with this light is that it is not mountable due to its depth of approx. 6" in a standard stud wall in front of a block wall, or a small profile stud to block wall.

There 3 small lecture halls and 2 large assembly type halls, there’s approx. 40 of these lights in all the walls + - , this same light is embedded in the concrete steps, I was not around for that yahoo.

The RFI's have be answered at a snails pace, the error was spotted three months ago, there is a paper trail!

Edit for phonics
