To answer the question above.. they see 36A running... yes this might be correct but there is something called "in rush current". This is a spike in voltage and amperage when first turned on. It's like your car... whey you first fire it up... the rpms are high... then it goes back to a normal idle.. :)

Use power over voltage calculation.
Power= 4kW or 4000watts
Divided by
Voltage = 220V
= 18.18A
So you basically can rate the breaker for 20A
