when you are installing cathodically protected underground systems you
should make sure that anode lead wires and monitoring wires are? -
ANSWERS-back filled with care and left slack to provide flexibility
when sacrificial anodes are installed they should be? - ANSWERS-back
filled with native soil soaked with three to five gallons of water
connections between anode lead wires and structures that are to be
thought of you protected should be - ANSWERS-thermite welded or
made by means of pressure type grounding clamps
in the absence of specific plan installation of anodes used for the
cathodic protection of underground piping systems should be

cathodic protected piping must be electronically continuous.
unconnected pipe in the system should be bonded with? - ANSWERS-
number 12 TW or THHN stranded or solid wire
while in some cases a single anode might be sufficient for providing
cathodic protection of a piping system it is recommended that more than
one anode is used for what reason - ANSWERS-a damaged accidentally
occurs to the lead wire of a single an ode or if some other malfunction
occurs the additional backup anodes will be available to protect the
