Junction box mounting locations there are two options for mounting boxes that are wholly contained within the attic.
Cable box survive in an attic.
According to agricultural engineer b r.
Other than that i don t see any problems.
Stewart attics without air conditioning can reach up to 160 degrees fahrenheit on a hot day and that s way too hot for your electronics to survive apple recommends using their computers at between 50 and 95.
By using a drill bit sized large enough for the cable.
Runs of nm cable must be supported at least every 54 inches.
The temperatures here in attics get into the 150 range which is way outside the operating specs for most electronics.
These methods will work for any cable telephone network thermostat power etc.
On a single story home or the the upper floor of a multiple story home this means accessing your attic to run wire.
Since the network cable will be run in the walls and the attic would code dictate that i use riser cmr or plenum cmp rated cables or will general.
The cat 6 cable runs will follow the existing runs for cable tv coax in each room.
General cable support.
You could create an insulating box and route it to the a c system to keep it cool in the summer.
Keep in mind that support does not always mean fastening the cable to framing.
I plan on replacing the existing coax faceplates with keystone faceplates with coax cat6 keystone jacks.
A typical usb2 cable has 4 wires.
Check out the working temperatures in the owners manual.
Cut solder heatshrink etc.
How id do it if you put your cables to the edge where the apex of the roof meet the ceiling so you basically end up with your wireing loom at the edge of your attic then clip your cables along the ceiling joists 50mm from the plaster board then its clear of insulation and if you need to lay a floor you can but do try to avoide drilling hole through the joists as you will not meet the.
New lighting cable computer networking and sound systems can all require wiring that may need to come through the ceiling.
They also must be secured within 12 inches of an electrical box that includes a cable clamp or within eight inches of a box or enclosure without a cable clamp.
If you are just using the usb cable for 5v power then it should be easy to modify the cable and extend it so that the power supply is inside or easily accessible.
You can attach them to the joist s side surface called the face or to the joist s top surface called the edge.
Since insulation is combustible you must install face plates on all attic junction boxes to prevent contact between bare wires and insulation materials.
