  1. It will also require Building Regs notification as you are replacing a Consumer Unit and installing a new circuit plus you are feeding a new point in the garden. That also doesn't look like a consumer Unit just a junction box. Consumer Units also have to be metal since Jan 2016 for domestic installations. Have you had an Electrician round for advice?
  2. That PS is rated at 5Amp 12Volt. Do your calculations and that will tell you your current demand. Although those PS are rated at 5Amps I wouldn't want to run them at max capacity for very long
  3. I use Tiny XLR connectors. Pins only rated to 5A but should be plenty for dew heaters etc but a fraction of the physical size
  4. It'll be fine. Insulation for 230V cables is rated up to 1000V
  5. CEF sell it by the meter.
  6. I used these for my Bee Hive monitoring setup. It is the 40W panel with a 12Ah 12V SLA. My system takes approx 150mA and this struggles in the winter to keep the battery topped up for an overnight run in the winter. Use one of the online calculators to determine the size of panel To charge multiple get an MPPT charger as this will allow you to connect multiple batteries and this type of charger will maximize the energy available from the panel You can't mix the types on one charger. You need to set up whether it's Gel, SLA or Flood as they all have differing charging characteristics but you can connect multiple chargers to one panel
  7. One of the guys down our flying field has one of these. Pretty neat bit of kit
  8. If the power to the shed is already protected by a 30mA RCD you don't need one in the shed. It called discrimination.
  9. The RA axis bearing preload should be hand tight and not use a wrench. You only need enough to just take the play out as any force will stall the motors once loaded up with gear. They always do them up to tight at the factory
  11. This one and there are loads more
  12. You need to remove the red bung pronto. Why didn't you run the all of the Negative cables to the battery terminal rather than have a floating join with the screw. They also look like 40A fuses (Orange) and I would have run a thicker cable from the Battery + to the fuse box Other than that it looks nice and easy to use
  13. This was taken with a 200P-DS and Canon 1D MkIII (Whirlpool Galaxy)
  14. 0.75 meters is deep enough for SWA. Lay a bed of sharp sand in the bottom, lay the cable then another layer of sand. Run a length of yellow danger cable tape over or even better use some of those roofing tiles you have to the side to cover then the tape. Then back fill. Make sure you leave far more cable at the ends than you think you will need as mistakes will be hard to rectify
  15. The connectors are rated at 5Amp so will be OK. For the current draw take the wattage of the dew bands and divide by 12 to get the current I(amps) = W(watts)/V(volts) ie. for a 20Watt band I = 20/12 I = 1.67Amps at 100% power The canon, and guide cam will take little current so allow 0.5A for each as a safety net. The manufacturer may have the specs for the focuser. Worst case is when stalled as this will ramp up the current momentarily. The HEQ5 specs say 12V 2Amp so allow 3amp to be safe. I would also add a few amps on top for future additions
