How can homework help parents?
Parental involvement with homework and engagement in their child’s education are related to higher academic performance, better social skills and behavior, and increased self-confidence. Parents helping with homework allows more time to expand upon subjects or skills since learning can be accelerated in the classroom.
Is 500 mcm good for 400 amps?
If the load is 380 amps or less, then you can use a 500 MCM. If the load is 381 amps or higher, you cannot use a 500 MCM. If you have not calculated the load, and you plan to use a 400 amp overcurrent device to protect a 400 amp panel, then a 500 MCM will not be sufficient.
How many amps can 4 0 Wire carry?
Wire Size and Amp Ratings
| Wire Size | 75°C (167°F) | |
|---|---|---|
| AWG | (mm²) | Copper |
| 2/0 | (67.4) | 175 |
| 3/0 | (85.0) | 200 |
| 4/0 | (107.2) | 230 |
How far can you run a 30 amp wire?
The reality is that you CAN run a 30A load on a 10ga wire but code calls for only 80% of load or 24A. Which is the same draw a 5500W element will draw. Length is the real issue, 50′ is the max for 10ga at 30A, you go up to 8ga for more than that.
Can you run 12 gauge wire on a 30 amp breaker?
“Twelve-gauge wire is good for 20 amps, 10-gauge wire is good for 30 amps, 8-gauge is good for 40 amps, and 6-gauge is good for 55 amps,” and “The circuit breaker or fuse is always sized to protect the conductor [wire].”
How long can you run electrical wire?
The following are the maximum lengths of cable you can use while still maintaining a 3 percent voltage drop for the given wire size (AWG) and circuit voltage….For 120-volt circuits:
| 14 AWG | 50 feet |
|---|---|
| 12 AWG | 60 feet |
| 10 AWG | 64 feet |
| 8 AWG | 76 feet |
| 6 AWG | 94 feet |
How far can you run 10 gauge wire on a 20 amp circuit?
85 feet
How many outlets can I run on a 20 amp breaker?
10 receptacles
Can I use 10-gauge wire on a 20 amp breaker?
Yes, you can use 10 AWG copper conductors with a 20 ampere breaker. There’s no problem using larger conductors, other than cost to you, and difficulties associated with working with thicker conductors.
Can you use 10 2 wire outlet?
10/2 with ground I presume? Safety wise, it is fine to use a larger than required wire. Wire Size for 240-Volt Outlets The minimum wire size for a 30-amp, 240-volt circuit is 10-gauge, but to prevent poor performance because of voltage drop, you should consider upgrading to 8-gauge if the outlet is far from the panel.
Is it OK to mix 12 and 14-gauge wire?
Anyway, the first subject is a bit touchy because it makes it difficult to perform an inspection when all of the wires coming into the panel are 12 but many of the circuits have 14 in them too. There is nothing against code mixing wire size for these circuits as long as the OCPD matches the smallest wire.
Should I use 12 or 14-gauge wire?
As long as you don’t put too many lights on the light circuit, you can usually control that circuit with a 15-amp breaker, as well as wire it with a 14-gauge wire. On the other hand, an outlet circuit controlled by a 20-amp breaker requires a 12-gauge wire.
Is it OK to use 12-gauge wire on a 15 amp circuit?
Because it’s thinner and lighter, 14-gauge wire is easier to run than 12-gauge wire. However, 12-gauge wire is acceptable on both 15- and 20-amp circuits, so some electricians use it exclusively when wiring a house.
Can you use 14-gauge wire on a 20 amp breaker?
You can not use 14 AWG anywhere on a circuit that has a 20A breaker. If you are putting 15 amp receptacles on a 20 amp circuit with 12 gauge wire, then you MUST use the screw terminals, not the back stab terminals. Just use the side terminals.
How many outlets can be on a 15 amp breaker?
8 outlets
Can you put a 15 amp receptacle on a 20 amp breaker?
You are allowed to use a 15 amp rated outlet on a 20 amp circuit simply because it is expected that the cord that’s plugged into the outlet should not exceed 15 amps (by code). Appliances which draw > 15 amps should have a 20 amp or higher cord and plug.
What happens when you put a 20 amp receptacle on a 15 amp circuit?
If your question is “can I connect a receptacle rated for 20 amps to a circuit designed for 15 amps?”, the answer is yes, because the receptacle can handle more current than the circuit is rated for. If you exceed 15 amps, the breaker will blow, and protect the receptacle.
Should I install 15 or 20 amp outlets?
Standard 15-amp receptacles are suitable for typical household appliances, lamps and other accessories. A 20-amp receptacle is for heavy-duty appliances and power tools, such as air compressors. Residential garages occasionally have 20-amp receptacles to accommodate larger power tools.
How many LED lights can be on a 15 amp circuit?
Each CFL or LED bulb typically gives the same amount of light as a 60-watt incandescent bulb while drawing 10 watts or less, which is equivalent to a current draw of 1/12 amp. Thus a 15-amp circuit can safely control 180 or more fixtures that use CFL or LED bulbs.
How many LED lights can you put on one circuit?
12
How many LED can lights on a 20 amp circuit?
38 lights
How many lights can I put on one switch?
Some light fixtures, such as lamps and ceiling fan lights, use multiple bulbs and draw more power. Most circuits in a home allow for 15 to 20 amps, so you can safely connect 1400 to 2400 watts of lighting on one light switch. That’s enough for 23 to 40 60-watt bulbs or 280 to 480 5-watt LEDs.
Can you put two lights one switch?
You can do this light switch wiring in one of two ways. The most common is to daisy-chain the light fixtures by connecting them to each other and hooking the first one up to the switch. The other way to wire multiple lights to one switch is to connect all of them directly to the switch in a “home run” configuration.
How do I add more lights to a switch?
You can usually install a light fixture between an existing one and the switch by cutting the cable to the existing fixture at the location of the new one, inserting the ends of the cable into the electrical box for the new fixture and pigtailing the new fixture onto these wires.
How many amps do LED lights use?
When Dave connects incandescent bulbs to an amp meter, they draw up to 1.6 amps, but when LED lights are used, they only pull about . 26 amps. The difference is significant, especially for RVers who do a lot of dry camping.
