I'm doing some backyard work putting in a concrete patio and rebuilding a deck. While I've got the deck torn down and no patio in yet, I'm contemplating putting in a run of wiring for a spa that won't be connected to the main breaker inside the house. I figure this will help reduce the cost of an install when I'm ready to move forward with the spa. The distance from the main breaker to my future location is about 30 feet away; roughly 15 feet inside the house and then another 15 feet outside. The biggest spas that I've been looking at need a 70 amp gfci sub. Would #4 THHN be suitable for this(something like this [url]http://www.wireandcabletogo.com/4-3C-THHN-PVC-Tray-Cable-with-Ground.html)?[/url] My indoor run would be in my unfinished basement along the foundation, would this have to go in conduit or a raceway? Once I get outside the house would I run this in a service ell down in the ground to pvc conduit at 18" and then back up and terminate it in a junction box or something near my intended use? I would not connect the wire to the main breaker and just leave it coiled up inside safely away from the main where hopefully an electrician could connect everything at a future date. The big thing I'm trying to do is get all the digging and trenching out of the way now while I've got easy access to the ground and put some wire in place. Once the deck is rebuilt and the concrete patio put in place, I figure this is going to be a much bigger job. Does that sound like a reasonable plan that would hopefully save me time and money in the future? Thanks! -Paul

Hello, Quick question: is there some way I can limit how much voltage something draws on a power source? For example, can I limit a 24 volt motor to only draw 12 volts from a power source? The issue I'm having is a motor that takes 12-24 volts tries to suck 24 volts out of a 12-volt power supply. The power supply is reporting "power trouble" as the motor is trying to get 24 volts- something the power supply can't provide. The "fuseless protection monitoring algorithm" then cuts off power. So... what can I do about this? Thank you all so much for any help you can give me! If I posted this in the wrong forum section or something, I apologize in advance! Sam
