Need to run new wire down to my bilge (old ones looking a bit green !!).

Where & what should I be looking to source (type & gauge - it's a 2000gpa pump)??

Could I assume that the likes of BCF would stock 'correct' marine grade wire, or am I
better off with the likes of Jaycay/Supercheap??

Slug Jaycar and RTM have tinned 15 amp wire.

You want marine Grade tinned core, RTM should have it, and I know BTC have it.

Thats a big pump, i guess it would draw somewhere between 10-12 amps? Do you have the model?

You could probably get away with a 20AWG wire, but I dont know how long a run you will need, so you might want to jump up to the next diameter. I think 20AWG is sold as a 3.5mm or 4mm cable, and should be right for up to 15 amps comfortably. maybe jump up to the next size to be safe, from memory that carries about 56a. I ran the next size up to my Deck Wash just to be sure, but via a relay so I wasn't running that much current up to my instrument panel.

Thanks Guys - I gotta get out more .... (didn't know RTM existed !!).

Pump is a TMC2000 (2000gpa - probably a bit of overkill??) - recommended 15amp fuse.

Another stupid question - if they're wired incorrectly (ie +'ve to -'ve ), will they run 'backwards'? - or does it not matter?

It depends on the logic - my guess would be that its very possible.

I get all my wiring from cooldrive or Rtm.
Yea it's a electric motor, reverse the polarity and it will turn the other way.
Make sure you use a proper waterproof connecters or solder the wire as standard automotive crimps do not last.
4mm wire will do just fine.

Use dual wall heat shrink on your connections, saves black rot setting in.

Thanks guys for all your advise

Is that the same as green rot
