ballasts-120V or 240 V
Comments (13)Just to be more precise, Lermer is almost right. It does not "take more energy to increase from 120 than from 240" - what it takes, is more windings of copper wire, and this results in slightly greater losses in the iron core and copper windings. Because you have to provide a bigger "electrical leverage", and due to facts of life with electricity, increased leverage comes with the cost of higher losses. Losses in copper/iron systems increase by the square of the current, so if we need twice the current, losses are 4 times as much, in proportion. That means that for instance a 400 watt ballast might lose 20 watts if using 240V but will lose maybe 80 watts if using 120. (double current means 4 times the core loss) That might mean an extra 60 watts of loss, or 15% of the 400 watts. (this is where the 18% figure from lermers post comes from - he is providing a simplified almost correct explanation, and is pretty knowledgeable, although always verify everything for yourself independently). However, the TOTAL HEAT, will be still either 420 watts one way, or 480 watts the other way - both ways still put out lots of heat to get rid of, and the savings in electricity by using 240v are only justified for a very large operation, and probably only if u are handy with doing the wiring urself - it is actually very easy, easier to wire, than for example do plumbing. For instance, if my setup called for 6x 400 w ballast, i would consider running 240, because it would only take one half of the amount of wire, and standard house wire will handle up to 300 volts. For instance 15 amperes of 240v would supply the 6 ballasts above, whereas if i was running 120 volts, i would need 15 amperes TIMES TWO, or double the amount of wire. The space on the electrical panel would be exactly the same - 2 separate 15 ampere breakers in one case, and 2 ganged 15 amp breakers in the other case. But the ganged breakers would be served by one cable, and the separate breakers would be served by two cables. so 240 v will give a neater job, because it uses one half of the amount of cable, if u have a large enough operation, and there might be a 15% savings in electricity, but the TOTAL HEAT will still be huge, and the lamps will still all be just as bright. The price of 240 v electrical plugs, and 240v electrical receptacles is MUCH more than 120v plugs and receptacles, but now it becomes a question of what are you growing and will your growing profits easily cover these costs. In terms of hiding this electrical useage from "the man" - that's another story, especially with modern meters that the utilities want to install - "smart meters" that determine exactly at what point ur power is being turned on and off, and very easy to spot a large indoor operation that is being turned on and off always at the same time every day, or a consistent on and off pattern of significant amperes.

Comments (4)I found this on E-HOW. ============================= Tips & Warnings If one of the spark plug sockets is empty, then your spark plug was forced from your engine during the blow out. In this case, replacing the spark plug and wire is mandatory. ========================= Really ?? !! I wondered about that but this removes all doubt....See MoreFor Bill V, Question on Laying Out Tile Patterns, & etc.
Comments (5)Quite honestly, I think you did an exceptional job on it!! Keep in mind you're going to have things on the countertop, and those little pieces won't be nearly as noticeable as you think. It's easy for me to sit here and "monday morning quarterback" this. If it were me, I would've started on the right with ALMOST what you have on the left-- cutting the triangles off the blocks, and starting from there. Thing is it still would've laid out to the same size piece in the corner. Diagonal herringbone is a little tougher to figure out what you're going to end up with, so what I'll normally do is lay some out dry on a flat surface, and take measurements to see how it's going to work out. if I see I'm going to have a little bitty piece like that (as in so close and yet so far), I'll see if I can open the pattern up a hair along the length of the wall. 9 times out of 10, I can do it and it's never seen, and then everyone says how lucky we are that it all worked out to full tile! LOL Seriously, though-- I wouldn't sweat that little piece. Where it's important-- at the far end of the counter, it looks great, and that's where it WILL be seen. 2) What is your opinion on a smallish floor and sizing of tiles? I've heard that you're supposed to use small tiles on small floors and larger tiles on bigger floors. I say, use what you like. I've gone in the opposite direction on BOTH ends of that, and it looked great. It's all about what YOU like. 3) What are your thoughts on tile patterns and sizes of rooms? With respect to patterns, the only opinion I'll give you is to try and stay away from a square soldier course pattern (just regular setting the tile in straight rows). The reason is that it "modulates" the room. IOW, it breaks the floor up into "modules", whereas even just turning that same pattern diagonal, it takes that effect away. Using your Versailles pattern, will do that even better, even laid straight. With smaller rooms, this isn't nearly as important, but the bigger the area, the more this makes a difference....See MoreVytex v. Sunrise v. Okna
Comments (16)I agree that a decision should not be based on that alone, however it is what it is, and should not be completely discounted. There are only a handful (no more than a dozen on the list that I saw) of the hundreds if not thousands of companies nationwide that were singled out by the FTC. The actions must be pretty egregious to warrant such a response, and it raises an eyebrow at the very least. I believe that several of the other companies on that list are now out of business. Often times there may not be one big hairy issue that indicates the way a company does business, but an array of smaller things that can fly under the radar can often establish a pattern. Take it for what it's worth....See Morefloral_uk z.8/9 SW UK
