What is the difference between elcb 30mA and elcb 300mA?
An ELCB is an Earth Leakage Circuit Breaker and is a device used for safety purposes to detect stray voltage or current on a metal enclosure in order to prevent shock. The two types of ELCB are Voltage-operated and current-sensing protection. The difference between a 30mA ELCD and a 300mA ELCB is that the 30mA version will have a much higher level of sensitivity, tripping the device is a much lower current.
Is it suitable to apply voltage 12V 30mA to charge 4V 750mA battery?
No, the charging voltage needs to closely match the battery or BOOM!
What is the voltage across a load given that the current though it equals 30mA and resistance of the load is 1000 ohms?
Ohm's law: voltage is current times resistance 0.03 amperes times 1000 ohms = 30 volts.
What is the maximum current that can flow through a 5mm LED?
There are numerous 5mm LED manufacturors and they can have different specs. Consult the specification sheet for the component in question.The 500TSW4DF Super Bright White 5mm LED has a max forward current rating of 30mA on its spec sheet.The RL5-R8030 - Super-Red LED has a rating of 20mA
WHAT is the rating of earth leakage circuit breaker used for welding machines?
yes , it is required so that the leakage current from transformer/electrical windings to metallic enclosure of welding machine does not harm a person/operator & the current is rooted back to earth bajaj mahesh, asst fire & sec officer
Express 30mA as a number?
30mA is 0.03 amps.
What size breaker for 8kw 277volt heater?
32amp 30ma rcbo
What is the load current of 90kw induction motor?
90/3=30ma
How long it will take to discharge a 9ah battery at the rate of 30ma?
9 / .03 = 300 hrs

Why BTS operated at -48 Volts?
All telephone exchanges use -48V DC Power supply. The negative potential is used to prevent electrolysis deposition at Battery terminals. Telephone normally work with about 30ma current driving a line impedence of about 1600 ohms (to drive about 5KM distance). Hence 30ma*1600 ohms=48 volts.
Where can you find a 30mA GFCI breaker for GE panel?
You can find a 30mA GFCI breaker for a GE panel at home improvement stores such as Home Depot or Lowe's, as well as electrical supply stores. Online retailers like Amazon or specialized electrical supply websites may also carry them. Be sure to check the specifications to ensure compatibility with your GE panel. Additionally, contacting a licensed electrician can provide guidance on sourcing the correct breaker.
What is the voltage across a load given that the current though it equals 30mA and resistance of the load is 1000 ohms?
Ohm's law: voltage is current times resistance 0.03 amperes times 1000 ohms = 30 volts.
Can 100 megawatts kill you?
yes. 1 watt can kill you, delivered in the right place with the right voltage. 30 volts applied from one arm to the other, which goes through your heart, with the terminals on pins stabbed into the arms, will produce more than 30mA. That is enough.

What RCD rating should you use?
The RCD rating you should use depends on the requirements of the circuit you are protecting. For general purpose circuits in homes, a 30mA RCD is commonly recommended. In certain specific situations or for specific equipment, a higher or lower rating may be appropriate. Consulting with a qualified electrician for advice tailored to your specific needs is recommended.
