[TheForge] Light bulbs and shop power

Fri Aug 3 20:38:04 EDT 2012

Not enough wire gauge or breaker for the tool and distance. Electrician is 
the safe place to start. That being said, dedicate a new 220 breaker in the 
main box, run large enough wiring to the shop (requirements can be found on 
line) to a sub panel to break the current down with breakers to the correct 
amperage and voltage as needed. Before re wiring try to figure the present 
need for power and add some to the requirement to figure out what is needed 
in the main panel and from there on out
