  • As a general rule of thumb, use 14 gauge wire for 15 amp service and 12 gauge wire for 20 amp service

  • Romax household wire, type NM is for indoor use and type UF is for outdoor/underground use

  • Electrical wire gauges decline as the wire gets larger 14-12-10 (i.e. a 2 gauge wire is substantially larger than a 14 gauge)

Hard Rubber Casters

  • 7018 welding rod is a deep penetrating and stronger rod


  • A325 and A490 Bolts are structural bolts with oversized heads

  • Box nails are used for more finishing type work where there is more of a danger of wood splitting.


  • To figure out footage on a roll, add outside diameter of roll to inside diameter of roll.

  • Take times .13 then take it times the number of wraps: (o.d.+i.d.) x .13 x #of wraps = footage on rolL
