Should house electrical cables be kept out of new thermal insulation?

Q. So I'm thinking of insulating my attic. I have a slab foundation and all my electrical runs through the attic. I know certain hot features (light fixtures, transformers, etc) need a certain amount of clearance around them so they can dissipate heat - that's in the electrical code. Do runs of individual cable, runs of multiple cables (which have to be derated just because they're near other cables) or junction boxes need to be kept clear of insulation too? The derating business makes me think they need space to dissipate heat, but I can't find anything on the topic. Also, if they are on the house side of the summer heat (it easily reaches 140 up there) wouldn't that be better anyway?

A. i have to laugh occasionally, when i think about how the NEC (National Electrical Code) has gotten folks so scared..Article 310 has always stated the ampacities of wires...#12 guage copper, according to Code, can handle 30 amps of current. (Article 310-16) although it stipulates that #12 will be attached to no more than a 20 amp breaker or fuse.

Think of your average bedroom in a house. 6 to 8 receptacles. per. room..max current load...1 clock radio...1 lamp. 1 television...potentially 5 amps on a set of wires meant to carry at least 30...Unless you have a factory in your house, with the continuous load factor figured....no more than 80% load per circuit breaker...don't worry about it...your house is never gonna get hot enough, to affect the wires...

keep the NEC rated clearances for the inductive loads....i.e. transformers,,,flourescent lites...Can lites need space to breathe, as they are resistive loads...both produce heat...give em room..

Continuous loads are a major factor with the NEC and NFPA.These are loads of three hours or more. i doubt that anyone on these boards has a continuous load...unless they are growing...something....

Keep your cables as best as you can on top of the insulation...let everything breathe...and unless your growing weed or making beef jerky, with lites...don't worry about the heat factor...remember...CONTINUOUS LOADS...


I was given a king size bed for a spare bedroom.Where can i find deals on sheets.?
Q. Would like to look online for miss matched or seconds. Need help finding some sites that offer these.
This room will only be used for the occasional over night visitor so i do not need a perfect set. Thanks.

A. Cheapest place I've found for sheets, especially kings, are off price stores like TJ Maxx and Marshalls, especially in there clearance shelves -- Ross Dress for Less stores are probably the cheapest. I have bought king sheets there for under $10 and even got a $120 king duvet and shams set for $14.99. I have never seen prices on line that can beat what you will find in these stores, except a couple of times when Target has clearance sales on discontinued items on their website. Last year I got a down comforter for $25 and a set of 300 count cotton sheets for $20 from Target online. It's hit or miss, though. Sometimes they don't have anything at all. Ross stores always have plenty of stock, and it is usually good quality cotton from brands like Laura Ashley, Springmaid, Lauren or Springs.


Color Schemes For a Teenage Girls Bedroom?
Q. I would like my room to look more appealing. Right now it looks to.... bland. I can't paint my walls, my walls are white btw. I have a dark wood bed, vanity, nightstand, and bookcase. I am getting a white desk, and a white mini bookcase or storage bench for my school work (haven't decided yet, im home schooled.) And i am painting my TV stand white. I wanted to get cream colored stuff but that didn't work out.

I was thinking the main colors in my room could be turquoise with accents of another color maybe a dark pink or raspberry. (y'all can choose other colors.) Also should I have another accent color of white or black?
