circuit breaker and wires

[moira]

gusto ko lang e confirm kung ano ang standard ampere rating ng breaker at ang number ng mga wires.
magdepende ba to sa mga loads?
pano ba yuun meron bang computation? halimbawa, ref, tv, aircon at mga bulbs, ano kaya ang specs ng breaker at wires ko?

sori po if hindi ko maipaliwanag ng mabuti, newbie lng kasi ako sa electronics and electrical.

sana meron tumulong....

sis may katulad na ang post mo d2

pakihalungkat nalang po

[akhen]

sa residential po ba?

usually 4 na relay(ckt breaker) ang ginagamit:
1. main 60A
2. lights 15A
3. outlet 20A
4. ref 20A

kung may aircon mas maganda nakabukod din ang relay nya 20A.

yung TV kasama na sa outlet yun...

size of wire:
1. minimum size of wire for lighting load = #14AWG, max. 12pcs. connected in one branch circuit.
2. minimum size of wire for power load (convenience outlet - C.O.) = #12AWG, max. 10pcs. connected in one branch circuit.
3. aircon (ACU) = depende sa specs ng compressor, in FLA - full load current (tingnan mo na lang yung label o sticker ng aircon), pero sinusunod pa rin yung minimum size of wire for ACU na #10AWG.

total load current ng residential +125%, dito na dedepende yung size of wire mo (feeder line / service intrance) at yung main breaker (AT).

sa mga branch circuit breaker naman, nearest to the AT.

ampacity of wire (based on 3wires in a single race way):
1. #14AWG = 15amperes (TW)
2. #12AWG = 20amperes (TW)
3. #10AWG = 30amperes (TW)

salamat sis sa reply. now i know pwede na akong mag umpisa.

salamat din akhen.

by the way sis, ano ung (TW)? at ung (AT)? sa itaas?thanks in advance

sorry nga pala,

TW - type lang ito ng wire, marami kasing klase yan sir, merong TW, THW, THHN. ito yung mga kalimitang ginagamit sa mga residential electrical installation. magkakaiba ang mga wire ampacity nito. pero basically TW ang ginagamit kasi mura sya.

AT - ampere trip ng circuit breaker. ito ang term na ginagamit sa mga circuit breaker.

estimate the fuse/CB rating based on wire ampacity...and estimate the wire size/ampacity based on loads.  madalas yata jan galing ang sunog from electrical fault kasi nasunog na ang wire. di pa rin nagtrip ang protection kasi oversized.

kailangan magkakalapit lang silang lahat.

TW =  type of  insulation

yung AT is at command hehehe 

[luis]

TW-thermoplastic wire (kind/type of insulation) AT-ampere trip (rated current of the C.B)
