3Kva UPS

[Mr.Wikirana]

3Kva UPS එකකට ගෙදර AC- Air Conditioning ( ගෙදර AC එක භාවිතා කරන්නේ නැහැ ) එකට එන Power input 15 AMP සොකට් එක හරහා එන ලයින් එකෙන් ඉන්පුට් දුන්නොත් ඇති වෙයිද. ගෙදර තියෙන්නේ 3 phase එකක්.

UPS Plug input එකේ ගහල තියෙන්නේ 18 AMP input කියලා.

It seems like you're asking whether a 15 AMP breaker in your house's AC power supply can handle the input requirements of a 3kVA UPS, which specifies an 18 AMP input.

To clarify:

• Your breaker: 15 AMP capacity.
• UPS input requirement: 18 AMPs (according to the label on the plug).

In this case, the 15 AMP breaker is insufficient for the 18 AMP input required by the UPS. Breakers are designed to prevent overloading and overheating of circuits, so using an under-rated breaker (15 AMP) for a device requiring 18 AMPs could cause the breaker to trip frequently or even present a safety hazard.

To fix this, you should upgrade to a breaker that can handle the 18 AMP input, which could be a 20 AMP breaker for some margin of safety. Additionally, ensure that the wiring and other components in the circuit can also handle this increased current.

It’s also worth consulting an electrician to ensure everything is correctly sized and safe.

according to the label on the plug. Not clear. Is the plug can go upto 18Amps or UPS required 18Amps.
If it it 3Kva, it won't require 18A.
