  1. Burying cables requires attention paid to de-rating the current carrying capacity of the cable. Heat is not dissipated underground as in free-air. Be sure and check the National Electrical Code for the proper application.
  2. Here is mine. I'm bringing 240 VAC from a 30 amp, 2-pole breaker. Each phase is GFCI protected under the rain shield. More than enough to run 12,000 mini-lights.
  3. I wouldn't be caught dead without them.

Everything runs together, A/C and all, with 1200 static mini-lights and a light snow machine without tripping the breakers on a 150 amp service. Your OK! You may need some more sub-feeders to expand your display.

  7. In my electrical district, there is no cost to increase the service and meter from the power company. However, your new power panel, circuit breakers, and work for that increased service will be expensive. :shock: Be sure to tell them you are adding a welder and power tools.

  9. You can drive a seperate relay with the DMX channel, which contacts will handle the additional current. But dimming won't work with the relay. Or select a silicon controlled switch, solid state relay,or a triac to do the job. Google it for a schematic.

Per the National Electric Code (NEC), Table 400-5(A), column B+, SPT-1 & SPT-2 is rated for: 10 amps - #18 AWG 13 amps - #16 AWG 18 amps - #14 AWG SPT-2 is heavy duty with extra insulation and has nothing to do with the current carrying capacity, per NEC, Table 400-4, All Plastic Parallel Cord, Thermoplastic insulation. I suspect the SPT-1 plug & receptacle is rated for 7 amps and the SPT-2 plug & receptacle is rated for 10 amps, although I have never seen a specification sheet on them stating that rating. Since

  13. What I do is, first turn everything off. Then, using the utility program I bring on one controller at a time and run it. When the offensive controller or light string trips the GFCI, I know which channel to look for. Then, spray the connections with WD-40 (that stands for Water Displacement, mixture or formula # 40). Good Luck! KB5WZE
  14. Plagiarism is the spice of life! How else does one learn? When the Russians copied our B-29 after WWII, they copied the exact patched bullet holes on every replica. :laughing:
  15. Has something happened at You Tube? I can no longer view my video, log-on, obtain another account using my email address and so on. Is there another place to post video clips of Christmas displays?
