Hi guys

I recently built a snake rack which uses 2 x 30watt heat cable. No matter where I plug it in my flat the earth leakage keeps tripping after about 30mins or so or as the wire heats up. With this happening I decided to plug it into a plug where I disconnected everything else and it ran fine for the night but when switched kettle on in morning it tripped. Would this be due to overloading the breaker ?
