Even if you push 1KW into it for less than 10 secs, it may cause the
resistive element to overheat and change value....it may not open or
burn up, but it wont be 50ohms anymore!!! Get a dummy load RATED at 1KW
ICAS (intermittant duty) and you will be safe...
Yeah you may be able use it at 1 KW...for maybe 10 secs MAX!!!..then
give it a minute OR MORE to cool down...but that's still IFFY!
