| I use anti-oxidant on aluminum conductors- no exceptions. Today I observed an electrician using aluminum conductors 1/0 and larger and he was not using anti-oxidant at all. What are the thoughts of the experienced ones here? |

| It is NOT code required, but I always use it. I coat the screw threads of AL terminations and lugs as well. |

| I too always use it regardless of size. |

| "It is NOT code required, but I always use it." I have not checked the listings in a long time, but at least at one point the listing required anti-ox on stranded aluminum for a couple wire types. You have to obey the listing. |

| A quick look in the White Book under Thermoset-insulated wire (ZKST) and Thermoplastic-insulated wire (ZLGR) does not show any requirement for using anti-oxidant on the terminations. Any manufacturer supplied instructions requiring the use of anti-oxidant would be in the form of a tag attached to the reel which you would never see unless you bought the whole reel. Even if there is no requirement for anti-oxidant, my experience is that connections made without the inhibitor are more likely to fail than connections made with it. For the 2â‚¡ or less that it costs per termination, I can think of no good reason to forego its use. |

| Many of the crimp type connectors already have 'goop' in them when you buy them. |
