    Default Simple Installation: Vampire Plug Question

    I'm doing a simple sparkleball installation outside a shop. There will be five sparkleballs under an eave. I want to make an extension cord with inline vampire plugs to mount under the wooden overhang (eave.) How much cord vs how many inlines can I do? All the sparkleballs are filled with LED lights. We live in San Diego, so weather isn't much problem. I'm a total novice at this and appreciate your help.

    The wire size is what will limit you, typically SPT-1 is 18AWG which can handle 10 amps, or 1200 watts ish. If the length is over 50ft or so, then subtract 30%, that would be 7 amps, or 840 watts

    With that description you wont have any issues with load. If that is what you are asking. Your longest run will be under a 100' I'm sure and maybe under 20 LED strings? Under 2A if so.

    Thank you! So I need to check each set of lights per sparkleball and add up their amps or watts not to exceed 10 or 1200 in the strip of SPT-1 I'm using. Correct? When I say novice, I mean I know nothing of any of this!

    Hey Wayne, so that means I could use 4 inline vampire females to plug in 4 sparkleballs on my cord of 8 ft? (with #5 at the end) Woo-hoo!

    One more question: Do the inline females have to be evenly spaced on the wire, or can I put them in anyplace I want? Does there need to be a certain distance between each plug? Thanks!

    You can put them any place you choose. That's the beauty of the inline sockets.

    Wayne, thank you for the link. I've bookmarked it. Question: I see that my plugs specify SPT1. I thought when I bought them they said 1 or 2. So I just made an extension cord with the plugs with SPT2 wire. It works-- but is there danger in using it? I've embedded it into one of the sparkleballs, and it will be hard to replace. So just wanted to ask.

    You can use SPT2 plugs with SPT1 wire, but not the other way around. You got lucky that it worked, the insulation is thicker on SPT2, so the SPT1 plugs have a hard time piercing it.
