At least once a week I see older 2 slot ungrounded
receptacles. Often, the main service panel and several branch circuits
have been properly upgraded, however, some older branch circuits were
not updated. You can see in the right picture above that not one branch
circuit in that panel contains a ground. Branch circuits may show a
ground with a tester if they are bonded to the main service panel with
AC or BX cable. (That was addressed in an earlier newsletter). So how
do you advise your clients when you see a 2 slot ungrounded receptacle?
The best option is to install a new grounded 3 wire branch circuit.
Another option is to install a Ground Fault Circuit Interrupter (GFCI).
The GFCI should be labeled “No Equipment Ground”. An electrician can
also run a dedicated ground wire from the service panel or from a
nearby grounded receptacle or branch circuit. A ground could also be
installed from another approved ground source (water pipe with proper
connections, external panel ground bus, etc). Many 3 slot grounded
receptacles are improperly wired because they may be over
amped. 15 amp receptacles will have 2 slots, with the neutral being slightly
longer and a ground. 20 amp receptacles can be identified as having a
perpendicular slot on the center of the neutral slot. Having a 20 amp circuit
breaker with 12 AWG on a receptacle rated for 15 amps would be over amped /
fused. Although we are not conducting a
technically exhaustive inspection, a good rule of thumb when it comes to receptacles:
- Any
fixed in place appliance should not exceed 50% of a branch circuit
amperage rating
Example: if the appliance is on a 20 amp branch circuit, it
should not be rated at more than 10 amps.
- Any
cord and plug connected appliance should not exceed 80% of a branch
circuit amperage rating
Example: if the cord and plug
appliance is on a 20 amp branch circuit it should not be rated at more than 16
amps.
