Will 95mm2 Battery Wire fit into a Mega Fuse Holder?

Ordered the 95mm2 battery cable and some 95-8 ring lugs. Now need to deal with the 400A fuse.

Having looked at Mega Fuse holders online, I'm wondering if the cable and lug will fit the holders.

Rather than just order a Mega Fuse holder, how can I be sure that my cable will fit?

Hope that makes sense!

Many Thanks

The holder will take any lug that has an 8mm hole. The question is whether there is an 8mm lug for 95mm2 cable, but I would expect so.

Since posting the question I've found a few Mega Fuse holders that specify a max cable size, generally around 35-50mm2. The largest I've found referred to is 70mm2.

There must be something that takes 95mm2 and a 400A fuse. I wonder if there's an electrical supplies shop where I can have a look around - Manchester.

I've ordered some 95-8 lugs from an eBay store, and Furnell Rideaux have them on their site.

Here's hoping:)
 
The fuse boxes don't really do very much except prevent accidental contact in the same way a terminal cover does. The fuses and cable lugs are bolted directly together. So if you need to trim the box a little to get your big cable in, that's no big deal.

Do make sure you have some suitably-sized heatshrink to cover the tubular part of the lug once it's fitted to the cable. This will probably remain outside the fuse box, so you want it covered. I ran heatshrink up to just short of the hole in the lug, minimum amount of bare metal showing for accidental shorts.

I had the same problem last month, I was coming off my battery bank with 95mm cable and to connect it to the mega fuse block I had to cut the plastic base and the cover to allow the lug to fit. It was not difficult using a Stanley knife. I also placed two extra fuses along side (they have dovetail slots to gang them all to getter) and fitted a copper bus-bar this also needed the base and housing cut away.
 
Someone on the canal boat forum has suggested t class fuse and holder as being more appropriate for 95mm2 cable - better heat dissipation? .... Much more expensive!
 
I wouldn't use a T class fuse - it is not necessary. But I would and regularly do use ANL fuses and holders for just your application. They will take any size wire without a problem.
 
You need to get these crimped with a hydraulic crimper.

You can save money by preparing the wires and terminals yourself, and will probably do a better job; especially if you read my Guide to Preparing Wires for Crimping, on my Bavaria Forum download page.

Read and digested. I've got all the stuff including a Dremel and some metal cutting discs, but where can I buy No-Crode?

Couldn't find it in B&Q or eBay, and can't seem to find it elsewhere online.

Many Thanks.

The only ANL holder i can find that specifies it will take this size wire, (up to 120mm2), is the Blue Sea from Merlin at about £50. There is a BEP holder for about £35, but this says up to 50mm2 or something. Am I going to have to pay £50 for holder, or am I missing a lower cost option?

It seems that this is no longer available, I've emailed Holts to see if there is an alternative. In the meantime, Contralube 770 is excellent stuff.

Note that the Holts product is mainly for battery terminals. Doing an eBay or Google search for Battery Terminal Grease will find many others such as this.

lug sizes

your best bet is to go the an electrical wholesaler, newey&eyre, edmunsons, cef, rexel, wallsal conduits - plenty to choose from and they will all accept cash payments, you can solder the lugs on if you have problems sourcing a suitable crimper (plumbing solder and flux works fine). 95mm is not that large our hand crimper does up to 120mm, if you get real stuck many of the wholesalers hire the hydraulic crimper and as you should be able to do the crimp in the shop that shouldn't be too pricey! (they are heavy and i wouldn't fancy one in our tender)

don't forget you are using the large cable mainly to reduce the volt drop and if necessary you could through crimp a 70mm to the end of the 95mm to get it into the fuse holder just use heat shrink over the crimp to insulate it afterwards. (use a 95mm through crimp and pack the space around the 70mm cable with a few extra strands of copper)

Over here I use Blue Seas fuse holders - about $20 for the ANL holder. There is this company as well. http://www.vteworld.com/content/electromech/fuse/html/anl/anlfuse.php

There should be a lower cost option in your part of the world.

Holts have confirmed that No-Crode is no longer available, I have updated the PDF "A Guide to Preparing Wires for Crimping" on the Bavaria Yacht Forum Download page. For general use, I suggest Contralube770, but for terminals on the battery the Wurth product may be appropriate.
