Macerator extension cord

I want to make an extension cord for a macerator pump. I want to add about 10 or 15ft to the existing cord so I can reach the TT battery. I plan on using 10 gauge wire. Is that big enough? I would like to add an inline fuse. What size fuse would be correct?
Has anyone made their own 1" extension discharge hose or is 3/4" all I need? Any suggestions would be appreciated.
  • Thanks everyone! It is a Flojet so your suggestions are exactly what I needed.
  • I made up a cord also but did fuse the line at the battery to protect the cord. Used 10ga outdoor lighting wire.
  • A 10g wire is fine. Check the fuse in the macerator and use that size fuse (but no larger than 30 amp). I made a cord for exactly that purpose and didn't fuse the cord because the macerator is already fused.
  • 10ga is good. If it's a Flojet pump there's a 20A fuse in the switch.
  • I just made one for my Turbo 300 and used 10ga... That was noted as the size on their website for the run I wanted..

    You haven't told us which macerator pump you have but instructions for the FloJet I have call for 10 gauge for a 10' to 20' run. However, I had some 12 gauge zip cord in my workshop and used it for the run from the tongue back to where I mounted a Bargman connector next to the waste gates, about 20' ... been working fine for years, no issues at all. To protect the cable I ran it through a length of black hose that's zipped tied to the trailer frame. There's no need for additional fusing with the FloJet as there's a 20 amp fuse in the switch handle. The run from where my FloJet is located to the sewer intake stack I installed on the house is ~ 50' so I use that length of 3/4" hose, as recommended by the manufacturer. I'd only use a larger diameter output hose if the run was much longer, over 75'. A series of 10 pics start here.
