A-C INTERFERENCE ON HD WHENEVER.....

Post by eliwhitney »

Hi dscalfano-(again)

Good that you have seen an improvement ! In case you haven't yet, on many HDTV sets, with the Remote at " settings ", there is as a part of the digital setup, a diagnostic
inquiry, wherein one may actually view the frequency, signal-to-noise ratio , strength in % and so on.

To keep a channel "locked", the higher that number, the better, naturally but someplace around 60 - 65, it will cause the digital signal to become unlocked - hence, your black-out.

As you make changes, rotate that attic antenna or move it outside, consider doing this
..(for each channel, too, as it varies)... to plot your progress.

There's nothing wrong with 14G romex as long as you use 15A components (receptacles, switches, breakers) and don't exceed the max number of receptacles and switches. 14G is much easier to pull and connect than 12G. I put in 14 new 12G circuits in my basement because I needed 20A service in a few spots and didn't feel like mixing and matching and it was a bit of a pain, especially when wiring receptacles in the middle of a run.

I wired my home theater myself. I used all 12G for the outlets. My plasma alone draws 783 watts and the AV receiver probably close to that or maybe even more. Not to mention the sub (self powered) and the DBS which is alway hot so probably consumes a 100W or more.

You can have a maximum of 10 duplex outlets on a 15A (14g) circuit, total wattage not to exceed 1800VA (or watts). 14g is infinitely easier to work with! I used it for all of my lighting to save money since copper has become very expensive these days.

The first thing you should do is identify which outlets go to what breaker. Then add up the wattages of all of the devices that will be on at the same time on those circuits (there should be a wattage rating on the manufacturers id/serial # plate). They cannot exceed 1800W.

In most commercial construction the outlets have to be identified externally as to what breaker and where it is. Not a bad idea for home electrical either. Overloading your electrical wiring is very dangerous. The wires can get hot and sometimes it takes a while for the circuit breaker to respond to the overload condition. I had an plastic outlet strip catch fire once because the 15A internal circuit breaker wouldn't pop. 14g is perfectly safe as long as you don't overload it.

On a 20A (12g) circuit you can have up to 13 duplex outlets (per branch) and a maximum total current capacity of 2400VA. I am still having "trigger finger" issues from terminating and pigtailing all of the 12g receptacles and circuits in my theater. I have 9 20A circuits (2 - gfci outdoors - 1 for an outdoor fountain and another with a digital timer for an air compressor), 1 220VAC for the HAC and 3 15A for lighting.

By comparison:

A high powerted microwave oven can consume almost 1500W by itself as well as many small space heaters.

My coffeemaker draws 1200W.
