Proffesional Electrical Advice Needed

[Zero Revolt]

Hello again everyone. Well I am happy to say that construction of my grow room is completed. I have one final problem to face that I have not encountered before and I am by no means an electrical expert. When I power up my grow room everything runs fine for a short time then the equipment I have installed ends up throwing the breaker switch and shutting down half of the house. Does anyone know of a way to correct this issue that I am having? Here is what is running in my grow room when the power fails. 400watt HPS light w/ external ballast, 180cfm exhaust fan, 2 wall mounted fans, light timer and a small electronic pest detterant device. now these devices are plugged into a surge protector which is plugged into another surge protector and then the wall. Any advice would help as I did'nt see this one coming. Thanks alot. and peace.

P.S. I should probaly add that my home is historical dating to over 100 years old. When I run my clothes dryer alone the power flickers minorly. Just wanted to add this so you know what I'm facing.

Man that sucks dick big time.

You arent even running that much juice.

Odds are you are gonna have to run a lot of different extention cords to other outlets on different circuits.

I have the same problem, just newer home...

I have to run an electric extension cord to another outlet in the garage.

You may have to run several....sounds like you might be on a 10 amp circuit.
