ICA: Electrical
Electrical Inspection: Inspect...
1) service drop
2) service entrances conductors, cables, and raceways
3) service equipment
4) servicing grounding
5) interior components of service panels and sub panels
6) conductors
7) overcurrent protection devices
8) a representative number of installed lighting fixtures, switches, and receptacles
9) ground fault circuit interrupters and arc fault circuit interrupters
Electrical Inspection: Describe...
1) amperage rating of service
2) the location of main disconnect(s) and sub panel
3) presence or absence of smoke and carbon monoxide alarms
4) the predominant branch circuit wiring method
who to recommend evaluation by for electrical
qualified electrician for all defects (licensed if that is needed in area)
NEC, AHJ, and your inspection...
NEC is about safety, AHJs will adopt NEC codes based on area, they also make
amendments to them, you need to be familiar with your areas codes and practices
so you know what us safe or not for your inspection
most common wiring
non-metallic sheathed cable
, 2 objectives of installing an electrical system
-provide safe way for electricity to enter home, perform work, leave the home
-dissipate excess heat generated as electricity does its job
load
any thing that uses conducted electricity through a circuit
hot wire
current with energy
neutral wire
path energy travels through to complete circuit and return to source
amps or amperage
amount or quantity of the electric current
volts or voltage
pressure behind current
-pulls the current on an electric system
multi meter device shows...
volts
ohms
resistance to current flow of wires or other conductors in the circuit
-this generates heat
watts
rate of work or power produced by the energy current
doubling the current
quadruples the amount of heat generated
service drops
overhead supply from utility pole
