Two additional black wires pushed into to the upper half (holes) on the back of the switch. This is an older switch in an older home. 40 years old apprx.I have bought a single pole switch which has a left side green screw and two gold screws upper and lower on the right side.

I have a power over Ethernet (POE) device that provides

I have a power over Ethernet (POE) device that provides power for four cameras, the POE requires 76.8 watts to operate, each camera needs 12 watts to operate.1-When performing loads calculation, is it enough to only consider the power consumption of the POE (76.8 watts) or also the power consumption of the four cameras?2-What if the POE is getting the power from a power supply that can provide a maximum power of for example 200 watts, do I consider only the maximum power that can be provided by the power supply in the loads calculation?3-What about the surge arresters and fuses, is there any calculation belong to them needs to be done when performing loads calculations?

I am looking to put power and light into two sheds at back

HiI am looking to put power and light into two sheds at back of house. CU is in front of house, I am planning to run swa up front of house into loft space through loft and down wall at back of house into shed 1, total distance of about 23metres. To be clipped to wall throughout run. In shed 1 it will be terminated into a 3 way garage Cu (amendment 3 compliant) protected by a 40amp RCD with 1 x16amp mcb and 1 x6amp mcb and one spare. This will be used to power a 2internal and 1external sensor light and 3 double sockets. Shed 1 has work bench for power tools etc.From shed 1 to shed 2 I shall be using swa again for a 15 metre run along a clipped along bottom of fence to another 3 way garage cu as shed 1. This again will be used to power 4 light fittings and 7 double sockets plus some low voltage garden lights. Shed 2 is used as a store one side and summer house on other side by son and friends there will be a TV, router, and maybe some heating. One of the sockets will be an external RCD protected for lawn mower.Protection is to be a earth rod by cu at shed 1 and also earth rod by cu shed 2 also to use armoured and one of the 3cores of cable.My questions is what size swa to use.? I was planning to use some already in store which is 4mm 3 core for the first section then some 2.5mm 3 core for the second section.Is this providing enough supply for what I intend to do. I have been told by local sparky that 6mm on first section then 4mm on second section would be better. Any comments. As required I will get signed of and tested but want to my around requirements and do some work myself.Thanks mark.

I have a gfci outlet in my bathroom that does not give any

I have a gfci outlet in my bathroom that does not give any power when I plug in cords. Pen tester says the wires are live and outlet tester is reading "open hot".I checked the wiring and it's all correct. There is a 12/2 coming into the box and connected to the outlet.Only thing I'm not sure about is why the hot wire is on the outlet but the neutral is spliced to another neutral tail and than connected to the outlet. I think it's because maybe they left the neutral in the box cut too short, and I doubt is causing any issue.Also for more information my bathroom is next to my kitchen. The ceiling lights and switches for both rooms, and the gfci that is not working are all on the same circuit.I checked the wiring to the switch for the bathroom light and it's only one wire coming into the switch.Any ideas for trouble shooting? Should I check the ceiling light? Maybe the line for the outlet is jumped off the feed for the light and could be open or cut somewhere?
