Question

How many amperes, on average are allotted to a single bedroom circuit?
:) thx!

Answer 1

Typically a 15 A circuit - the National Elelctrical Safety Code generally allows 125% overload, so you could draw a little over 18 A before tripping the breaker.

Answer 2

I m building a room downstairs for my daughter. Lights are all LED these days. A 100 watt equivalent only draws 18 watts. That s 0.15 amps. So, worst case scenario for her will be a 1500 watt hair drier, ceiling light, LED nightstand lamp and her phone charger. Still well under 15 amps total. I see no conceivable reason to use a 20.

As for putting the light on a separate circuit: If it blows she can step out her bedroom door and be 4 feet from the main light switch for the basement, which is on a separate circuit. Not an issue, therefore. Smoke alarm is a lithium "10 year battery" type. Not an issue.

Single circuit, 15 amps. Plenty.

Answer 3

National Electrical Code dictates a 15A or 20A circuit. Most new construction uses 20A breakers with Arc Fault Interuption devices. Arc Faults are a new law for all bedrooms for 2005 NEC. The breaker size IS the circuit size, so for 20A breaker you must use 12 AWG wire. The old 15 amp circuits can use smaller wire, 14 AWG. I dont have my book here so I cant look for you but I think you can have 9 - 11 recepticals on a 20A circuit. There must be an outlet every 12 linear feet of wall. (any place along the wall you are standing there is an outlet within 6')

Answer 4

in a typical bed room, if you have a 15 amp circuit, you can use 80% so .8 * 15 = 12 amps

for a 20 amp circuit .8 * 20 = 16 amps. Most bed room only have one circuit that feeds all receptacles in that room.

more than 80% and the circuit if in danger of being overloaded. The 80% rule is used in design calculations.

Answer 5

A bedroom would be served by part of a 15A. AFCI circuit.
There could easily be more than one bedroom on the circuit.
In general, one would allow for about 100W. per outlet,
(except in the case of an air conditioner outlet which would have its own dedicated circuit.)

Answer 6

NEC Section 210-21(b)(2) says you can only load breakers to 80% of their nameplate rating. This means a 15 amp breaker will only have steady-state loads of 12 amps.

For dwelling units, National Electric Code (NEC) Table 220-3(b) calls for a designed load of 3 watts per ft². This includes lighting and receptacle loads and assumes unity power factor.

Answer 7

15 or 20 amps generally speaking. heavier circuits are put in for many window air conditioners.
if the rules were followed by the electrician you can look at the outlet and know its rating
an outlet like this

I I
o
is rated 15amps

-| |
o
is rated 20 amps

Answer 8

usually it's on a 15 or 20 amp fuse circuit
