Electrical Question Mg zs 120

Hi



is it safe to have lots of electrical items on and be sat still in traffic?



yesterday it was bad rain and poor visibility, I had both front and rear fogs, headlamps, both wipers, window heater and a/c on to stop window mist, fans etc. Everything was ok although the wipers started to go really slow so I turned stuff off as I became worried the engine may cut out. If I had left everything on would the engine have stopped? Is it not advisable to have lots of items on at same time?



Thanks
