Im trying to get the amount of voltage needed to power this spa. It was given to me by a friend of a friend (freebie). No manual or anything. It looks to be 110V, but want to make sure before I run the wires. Cant wait to get this thing hooked up to see if it works. Pics are attached. Thanks

If the spa was hard wired, it was most likly 240V. Check the control box, often they will have a schematic inside the cover. Also, you will be able to determine voltage by how many power connections there are. 240v spas typically use black, white, red, and ground, whereas 120V spas use typically just black, white, and ground.
