the standard charts say that 50mm tri-rated can do 200A presumably all day for 20 years
Does anyone have short time ratings? We need to run a 280A pump for a day. Pump is on softstart and runs for 90 secs about once every 4 hours.
Cables would be about 5m long.
Gut feel says it will be ok but would value opinions of others
