Anderson SB50 extension cable

[BradC]

I always carry a decent set of 5M jump leads (35mm2). These will pretty much start anything with no waiting. They're not small, not light but incredibly effective.

I'm working my way through converting most of my stuff to Anderson SB50 connectors to standardize everything. I have a pair of 1/2M SB50 to croc clip leads, plus the usual SB50 to cig-lighter Male/Female and pretty much everything you might need.
I have 14m of 6B&S left over with the intention of making an SB50 extension, but I'm stumped as to how long to make it. I figure if it's short enough it'll double as a jump lead with the croc clip adapters and I might be able to leave the big ones at home, but the longer I make it the more useful it could be.

So in lieu of asking for direct advice, this is more of a "what do you carry and why?".

Hi Brad and you can easily jump start using your full 14m as an extension lead.

The cable size and length is only a small part of what is needed to carryout a correct jump start.

This link will help with why your 14m lead would be fine.

I have a set of leads similar to yours from my truck days. Hard to be without.

My OKA has a demountable winch that fits in front and rear tow receivers. It is connected via Andersons. In the event pictured in my avatar i discovered this to be a stupid idea, as getting the winch out of its cupboard and mounting it, in that unbelievably slippery mud, was bloody difficult. The intention is to mount two, front and rear. But I'll leave the Anderson plugs for precisely the reason you describe. Such a simple idea.

That's an excellent link, Tim. I've taken the liberty of copying your posts so I can read and absorb.

would the 50 Amp Anderson plugs be capable of supplying enough current to the dead battery without issue?

I've considered converting my jumper leads into an anderson extension too, but could never make heads nor tails of the specs of the SB50 plugs.

I've found specs that seem to indicate that (genuine) SB50 connectors are OK up to 120Amps, and that voltage is good up to 600V AC/DC.
Does this mean that the plugs themselves are good for up to 3000W of power handling?

Or that only a maximum of 50/120Amps, even at only 12v is acceptable(ie. 600/1400W max)?

Not being an electrical type, the spec sheets read like gobbeldygook to us less knowledgeable on such matters.

And obviously these ratings are for genuine Anderson plugs, and I assume many folks acquire generic/cheapo plugs from whatever source, and they won't be genuinely rated as highly as the real McCoy(I assume).

Voltage is irrelevant to the connectors excepting for insulation breakdown. They are rated for XX amps. If you put XX amps through them, the combined resistance will drop YY volts with the resulting power dissipation will be XX*YY W. The actual applied voltage doesn't matter, only the resulting drop through the connector and that is purely a factor of the current and resistance. Twinkle twinkle little star, power equals I squared R.
