AN electrician has just 1st fixed my house and took a feed an neutraul off the lights 3 plate method to a fan spur to fan which i am fine with (sometimes you see the fan spur on the kitchen ring thats all).what i am wondering is if i ever want to change the fan spur in the kitchen to a cooker hood spur may be in the future.how much does a cooker hood pull in amps is it basically what a kitchen fan would pull hardly nothing?would the cooker hood be perfectly fine on the lighting circuit?
