    What Gauge Wire To Use

    Hey all,
    Just wondering what gauge wires you all are using, my setup is Jeff's controler, and then 400 watt inverter, I have some 16gauge wire for my ACC line and some pink 12 or 10 that came from lowes but my problem is it will not fit into the terminals I have for jeff's controller. My origional Idea was to run the pink wire a + / - directly to the battery going into jeffs controller and then use simular wire to the inverter. Would I be better off just running the pink to a distribution block and then using the 16 from that?? The terminals are the 3M ones that hold 14 or 16 gauge and can hold 600 volts.
    What would a safe thickness be on the wire? I plan to have amps running in the near future too.

    Just looking at the ratings of my wire to see what they can handle... and I will have probably answered my own question, but any help would be apprecheated

    Here's a general guide to wires that I use. Sorry about the alignment, but the BBS ignores the spacing in the table.

    AWG AMERICAN WIRE GAUGE TABLE FOR BARE COPPER WIRE
    Compiled by Fr. Thomas McGahee tom_mcgahee-at-sigmais-dot-com

    This Table may be copied freely so long as credit is given to the author.
    Originally compiled for use by those building Tesla coils on the TESLA and
    TESLA-2 internet mailing lists.

    Compiled in April 1998 based on information derived from various sources.
    Since there were some discrepancies between data sources, the author has chosen
    not to just copy the numbers found in those sources, but rather to write a
    program that would generate the data based on a Best Fit mathematical model.
    The author has checked the Diameter in mils results against the data contained in the
    MACHINERY'S HANDBOOK, Twenty-First Edition, 1982, published by Industrial Press Inc.
    All numbers shown are accurate to +/- 1 in the least significant digit position.
    Column headings have been repeated to make the list more readable

    AWG = American Wire Gauge size from 0000 to 40
    Dia-mils = Diameter in mils (1 mil = .001 inch)
    TPI = Turns Per Inch [Note that this is for BARE WIRE. Insulation thickness varies]
    Dia-mm = Diameter in millimeters. This was included to help when dealing with metric Coilers.
    Circ-mils = Cross sectional Area in Circular Mils. ( circular mils = diameter in mils squared )
    Ohms/Kft = Ohms Per 1,000 ft.
    Ft/Ohm = Number of feet required for 1 Ohm of resistance
    Ft/Lb = Feet Per Pound
    Ohms/Lb = Ohms Per Pound
    Lb/Kft = Pounds Per 1,000 feet
    *AMPS = Conservative Amp Rating based on 750 circulare mils per Amp
    MaxAmps = Maximum allowable current based on 500 circular mils per Amp. Do NOT exceed this rating.
