WHY DO WE GROUND?

ProtectEquipment fromFault Currents

Protect People

SAFETY


4/73


Electricity will always follow the

path of least resistanceto ground.

Proper circuit grounding will keep electricity from using your

body to get to ground

Grounded Circuit Requirements:

Path is continuous and permanent

Ample capacity

Low Resistance

Circuit parts are bonded together

WHY SHOULD WE GROUND?

WHAT DO WE GAIN?

Prov ides personnel safety - #1 prior i ty

Prov ides a stable signal reference for

inst rument accu racy

Contro ls Radio Frequency emiss ions &

Electromagnetic Interferences (EMIs)

Prov ides a discharge path for sho rtc i rcu i ts and l ightn ing s tr ikes

EXOTHERMIC PROCESS

The exothermic proc ess is a simple, eff ic ient method o f

weld ing copper to copper or copper to steel .

This process uses a high temperature react ion ofpowdered copper oxide and aluminum .

Reaction takes p lace in a graph ite mold .

Mold w i l l last for 50 or more welds w ith prop er care.

This sys tem is very f ie ld fr iend ly, since i t is l ight and

po rtable and requires no ou tside power.
