we were running short on larger wirenuts the other day, and the answer to get thru the shift was 'skip the grounds' normally this isnt our practice, but it was 4-5 solid #14s, no real chance of coming unraveled if twisted properly. this started a debate tho as to if it was legal or not. a quick look at the codebook at lunch didnt answer the question. so just wondering, is there a code requiring the grounds to be wirenutted?
