[RE-wrenches] Splices in service panel

[Ray Walters]

Hi Mac;

I'm not sure I understand how you would extend the wires without 
splicing. BTW you only need to extend the hots, not the neutrals or 
grounds.
*NEC 312.8* sets a cross sectional area limit of 75% for the splices and 
wires inside an OCPD Enclosure.
I just found these inline splices to use instead of the infamous wire 
nut: http://www.idealindustries.co.uk/product/12/557/67825/.html
These should make for a cleaner install, and take less precious space, 
but I haven't tried them yet.
