[RE-wrenches] Battery Cable REvistied

[Mark Frye]

I recently worked with a telecom specification that required lead plated
copper lugs on the battery side and I have been using the same on my own
systems for some time now.
 
How important is it to use lead plated lugs on the battery side? Is tin
plated copper just as good so long as you coat well with grease etc.?

Hi Ray,

 

I have for my last 2 battery jobs used the Cobra X-Flex in 2/0 size with MTW
rating.


At the battery end I have found the Thomas & Betts 54163-TB lugs, available
at my local Grainger store to be a good match both mechanically and
specification wise (also the correct hole size for M8 terminals in my
Concorde AGM's).
On the usual electrical equipment end, I use a Greaves Shoo-Pin PT131FX20 as
the appropriate reducer to a THHN stranding #2/0 size (available through our
local Graybar store, drop shipped to my office). Because I am using a Sunny
Island, of course nothing #2 fits. so I have two Polaris style connectors in
the trough below the SI where I switch from the Shoo-Pins to four #1 THHN to
go up into the SI batt terminals (two conductors per pole).

 

In fact, I am wrapping up one of these installs right now.

 

Don't know if this helps,

 

-Glenn
