Many people use the wrong size cable for their systems but working out what power cable you need is actually very simple. Add all the ratings together. ie total each amp so a 2x50wrms amp would be 100, then add the totals together. This gives you a number representing the current draw, in amps, of your system. Then match the current with the length of the cable in the following table to give you the correct size cable to use.

Using thicker power and ground cables will allow your amplifier to draw the juice it needs from the battery more easily. You'll find all the power and ground cable you need available in our online Installation Store. Before you can decide on the appropriate gauge wire for your installation needs, you need to figure out the current demand of your system. To do that, you must ascertain the approximate current draw (in amperes) of your amplifier (or amplifiers).

The main purpose of your power supply is to run your trains. To run your train your power supply must supply energy for your locomotive, smoke unit, sound system , and any lighted cars. You may also need power for accessories like switches, street lights, building and house lighting or any other accessories. Your TOTAL POWER REQUIREMENTS depends upon the number of locomotives or motors, and ALL OTHER items that require electricity. The length of the track is not a factor.

Sizing an inverter is nothing but simple math. A TV may require 150 watts and the VCR you want to add with it may require only 100 watts. Just simply add the wattage requirement for all the appliances that will run at the same time. The answer is 250 watts for both the TV and VCR to run. However, it is recommended to always go slightly bigger (25%). This will ensure that the inverter will power all appliances safely. For more information, visit our Inverter Sizing page.

You will need a standard usb cable (the one that is included in the box when you buy the phone). Because you are going to use a usb cable you have to install drivers for this cable. You can find this drivers at the downloads page If you do not have this cable you can buy it from us. For now go to contact site to ask us for the cable. You can also buy it in every electronic store and ebay. It's often the same cable as used to connect digital (video) camera's to a pc.

The right answer to this question depends upon which subwoofer you choose. You'll find a recommended power range (in continuous or RMS watts) listed in the specifications for each subwoofer on this website. The lower number is the absolute bare minimum amount of wattage you need to get acceptable results. Generally, more power is better because bass notes are power hungry.

The small power inverters (350 watts and under) come with a cigarette lighter adapter, and may be plugged into your car's lighter socket. The small units also come with cables that can be clamped directly to a battery. If you want an DC to AC power inverter that will plug into your cigarette lighter, you must choose one that is 350 watts or less. Larger DC to AC power inverters (500 watts and over) must be hard-wired directly to a battery.

The first step is to determine how much lumber you’ll dry in a year. Then figure your average drying time for each of the species you’ll be drying, and you can calculate the size kiln you need from there. For example: you need to dry 500,000 board feet of oak per year. Fresh off the saw, oak takes about 28-30 days to dry, so you’ll be able to do 12 loads in a year. Each load will need to be 42,000 board feet to give you the 500,000 board feet you need for the year.

From the area you plan to heat, deduct approximately 5-10% and select the nearest mat down from that in the range . Select a thermostat to control that area or a single thermostat per installation up to the 16 amp maximum rating. It is the equivalent of taking out your loft insulation and increasing your boiler to cope with the extra demand.

Not technically, but some cable operators require that you do subscribe to basic analog cable TV service before you sign up for high speed Internet access. Check with your local cable company for specific information.

The maximum x-ray energy you need is determined by your sample. Thinner, low-density materials (e.g. plastics) require less x-ray energy than, for example, metals or very thick parts. You also want to make sure that your source has sufficient power to provide enough x-ray flux to give you a useful image signal-to-noise ratio. a rule of thumb, materials such as plastic or circuit boards are typically imaged at 50-70 kVp (kVp = peak x-ray energy; i.e. your source voltage setting).

That depends on what sort of bass impact you hope to achieve. If you just want to hear a bit more bass than your regular stereo speakers can put out, you can get what you need with an efficient 6-1/2" subwoofer driven by as little as 30 watts RMS. But when you're looking for really big bass, you'll need at least a 10" or 12" subwoofer and a minimum of 150 to 200 watts to drive it. Low bass notes are power hungry, and the more wattage you feed them, the better they sound.

The human neocortex has many millions of NCCs. For this reason we would need first an accurate replica of the NCC and then we will simplify the NCC before we begin duplications. The other approach is to covert the software NCC into a hardware version - a chip, a blue gene on a chip - and then make as many copies as one wants. The number of neurons various markedly in the Neocortex with values between 10-100 Billion in the human brain to millions in small animals.

No, the 810 and 820 series meters operate in using a "single ended supply" meaning you only need between 9 and 25 VDC to operate them. We sell very reasonably priced power supplies that accomplish this in a very economical manner.
