    Bought a Sterling 350w inverter at the Belvoir meet, installed it this afternoon, DC supply cables not quite long enough and I need an inline 60A fuse (why can't dealers tell you this at time of purchase? or don't they know:Angry:)

    Anyways, obviously unit needs to be as close to leisure batteries as possible, inverter was supplied with DC leads about 2 foot long, I need at least another 12-18 inches is this a safe length to add?? :Blush:

    Many thanks guys

    yes, but the wire needs to be at least as thick as the original or preferably thicker along its full length....not really feasible though unless you cut off the original as close to the invertor as possible and connect the thicker wire at that point.
    a thinner wire will carry more current over a short distance without overheating than a wire of the same size over a longer distance .

    if the invertor is 350w peak output, but lower constant output, then at peak output it will draw approx 29 amps so why a 60amp fuse ?

    if its 500w peak then it will need at least a 40 amp fuse.

    350w continuous 600w peak hence 60a fuse. :Eeek:

    Can you not fit it next to the battery and run the AC the extra distance?

    That's my back up option but battery locker space is very tight and downside is it'd be very easy to leave inverter switched on!
