This document discusses wiring devices and ground fault circuit interrupters (GFCI). It defines wiring devices according to the national electrical code as units that are intended to carry but not utilize electrical energy, such as switches, outlets, and receptacles. It provides guidelines for selecting wiring devices, including choosing a reputable manufacturer, looking for a warranty, and selecting materials that are durable and easy to install. It explains that outdoor outlets and those near water, such as in kitchens and bathrooms, should be GFCI-protected. GFCIs detect ground faults and interrupt current to prevent electric shocks. The document discusses how GFCIs work and the types of GFCIs, including receptacle and portable GFCIs

2. Our topic for today is about wiring devices!
• Do you have any idea about wiring devices?
I will give you 3 minutes to share your idea about wiring devices!
Clue! Maybe you are familiar with the pictures shown on the screen?
• Ok! so yun ay mga electrical materials or electrical devices na ginamit natin sa bahay gaya ng
Switches, receptacles mga outlet at iba
• What do you mean by wiring devices?
According to national electrical code or NEC a wiring device is a unit of an electrical system that
intended to carry, not to utilize electrical energy.
• These are the types of wiring devices

3. How to select wiring devices!
These are the guidelines when we select wiring devices
Specially when we plan on building our houses
1. Select a well-known industry manufacturer.
piliin ang kilalang company or manufacturer ng wiring devices like Panasonic at royu
sa panahon kc natin ngayon uso ang imitation,plagiarism o kopyador ng product ng my product
2. Look for a multi- year product warranty.
syempre pag gagamit ka ng wiring devices ay dapat pang matagalan kung maari ay aabot ng lifetime
3. Make sure that there is an easy and clear way to contact the manufacturers support.
kailangan alam natin kung san natin binibili ang mga wiring devices para incase na may damage ay
pwd nating ibalik ito agad
4. Check for a connected equipment damage warranty.
Check natin kung may warranty ba at kapag nasira ay pwede natin ibalik sa supplier
5. Always ask for manufacturer’s manual.
6. Select wiring devices which are well-made and durable.
7. Select materials that easy to use and install.
8. Select wiring devices according to the job requirements.

4. Lets talk the information about ground fault circuit interrupter or GFCI
• Outdoor receptacles as well as those in kitchens, bathrooms, and anywhere else near water should be
the ground fault circuit interrupting type.
Yung mga receptacles outlet na nasa labas ng bahay natin at mga receptacles na malapit sa
kitchen, bathrooms or malapit sa tubig ay dapat GROUND FAULT CIRCUIT INTERRUPTING TYPE
DAPAT DAW NATING GAMITAN NG GROUND FAULT CIRCUIT INTERRUPTER,
Ano nga ba ang ground fault circuit interrupter?
The GFCI is designed to guard people and pets from severe and sometimes fatal electrical
shock. A GFCI detects ground faults and interrupts the flow of electric current.
isa syang devices na kapag my shortcircuits or overload automatic na hindi nya padadaloyin ang
kuryente
Halimbawa: a hair dryer
(blow dryer) that is accidentally knocked off of a bathroom counter and into a bathtub filled with
water. The GFCI will stop the flow of electricity within milliseconds - of the hair dryer hitting the
surface of the water. If someone was in the bath tub, a painful shock may still be felt but the GFCI
will prevent their electrocution or serious injury.

5. How a ground fault circuit interrupter works?
Halimbawa“:
Meron kang toaster na luma sa bahay nyo at dahil sa kalumaan may
mga loose na syang wires at yung wire ay naidikit sa frame or housing
ng toaster at kapag ito ay sinaksak nyo sa outlet syempre ung frame or
housing ng toaster ay dadaluyan na ng kuryente.
at kung nahawakan mo ang housing or frame ng toaster anong
mangyayari sayo? GROUND at kung ang isang kamay ay nakahawak sa
metal or sa faucet ano ang pweding mangyari sayo? You will receive a
life-threatening shock. Pwede kang mamatay!
Pero pag ang oven toaster ay plugged into a GFCI, kusa itong
magtuturned of bago dumaloy sa katawan mo!

6. Types of Ground Fault Circuit Interrupters
1. Receptacle GFCI. These are the outlet that we used to call
“saksakan”
si john ay saksakan ng?
si sir Daniel ay saksakan ng?
2. temporary/portable gfci
pwde mo syang madala khit saan
para lang syang adapter
para lubos natin maunawaan ang portable GFCI watch this

7. NEC PROVISIONS ON INSTALLING WIRING
DEVICES
Mga batas patungkol sa pag iinstall ng wiring devices
6 feet ang taas ng wiring devices mula sa floor
