For making connections on
live electrical circuits as per
NFPA 70E you have to wear
these PPE

person who
was in it


Arc Flashes
9

• Mainly occur in electrical devices that are
480 volt and up.

• Motor control centers and substations are a
great source of faults.


Arc Flash Explosion
10

• Vaporized metal and ionized • – Forms the arc path through air
air: • – Expands to form blast wave

• Temperatures reach 35,000°F+

• Energy levels can reach 20-100
Cal/cm2

• Duration is less than 7/10ths of
a second

• Proportional to energy and
distance.


Damages from Arc Flash
11

• High temperatures burns to skin

• Melting of synthetic clothing to skin

• UV and IR burns to eyes and skin

• Temporary or permanent blindness

• Pressure Wave can knock you down

• Decibel can reach 160 DB

• Neurological effect of a magnetic field

• Temporary or permanent personality changes

Solution: Install MTAP
13

Time consuming tag
out and lock out
procedures are
eliminated and in
seconds you can
connect and collect
accurate data to
determine your motor
health.

MTAP2 meets both OSHA and NFP 70E
definitions for safe voltage

MTAP 2 Provides protection from Arc Flash
21

Before MTAP2 you need PPE to protect against Arc Flash
while connecting test leads & current probes

After installing MTAP2 there is no need to open the MCC door to make connections.
Test cable is connected to the connector installed on MCC Door
