What is fuse rating that can be selected for a 10 hp motor?
Answer: 10 HP motor is invariably 3 phase motor, and in India, rated for 440 V. Current at full load will be 13.1 Amp. Fuse rating will be more than double of this to account for starting currents, and correct rating will be 30 Amps for wired fuses.
What fuse to use for LED lights?
However, we must also allow for an additional 20\% higher Amperage fuse, much like we would add to our LED Strip calculation when determining the correct Drivers. We would then suggest that a 5A fuse will be perfectly suitable. Using this formula, we can now move on to LED Strips.
What fuse do I need for 240v?
100 Watts divided by 240 Volts equals 0.42 amps +10\% which equals 0.46 Amps. So from this calculation the ideal fuse would be 1 amp. However most manufacturers put a 3 amp fuse in the plug as standard.
How many amps does a 10hp single phase motor draw?
Full-Load Current in Amperes Single-Phase Alternating Current Motors
| HP | 115V | 230V |
|---|---|---|
| 5 | 56 | 28 |
| 7-1/2 | 80 | 40 |
| 10 | 100 | 50 |
| The voltages listed are rated motor voltages. The listed currents are for system voltage ranges of 110 to 120 and 220 to 240. |
What are motor rated fuses?
Motor circuit protection fuse-links have a dual current rating, consisting of a continuous current rating and a rating relating to the operational characteristics. The letter ‘M’ separates these two ratings, for example, 20M32.
How is transformer fuse rating determined?
In lieu of transformer inrush data, the rule of thumb is to select a fuse size rated at 300\% of the primary full-load current and round up to the next larger standard size.
What size breaker do I need for a 10 amp motor?
If you are connecting your 10 amp load to a standard electrical circuit in North America, a 15 or 20 amp circuit would be appropriate. If it’s a motorized load, I recommend a 20 amp circuit because inrush current at startup can “nuisance” trip a 15 amp breaker.
