- Hi Chaps, I am in early stages of designing a new PV project for an existing customer, there are two MPANS on this site, east and west. His new barn has just been built and the electrical installation is from the east MPAN. The proposed PV system is to be fed from the west MPAN, […]
- Looking for a bit of advice on bonding on a new build shed. The main water pipe enters the building in plastic/ alkathene so my understanding is that the main water does not need bonding. But the pipework then feeds out to a heat pump which sits outside the building so I would say that […]
- Hi, In the following they have a solar edge inverter but a myenergi battery and myenergi Eddi. Doesnt this create an impossible headache for the customer to configure their system properly? View: https://www.youtube.com/watch?v=sj1Uk-feg_M&t=137s

- A customer has asked me to fit an easee one EVCP. I notice that it has a type B RCD in it (I think). We are not supposed to fit a 'lower grade' RCD upstream, due to the blinding effects. Its not possible (at least not easily) to fit a type B RCBO into the […]

- This is at the mains unit end after a complete refurb. I've come from the inverter in the loft into the isolator, then into the left side of the meter and then the right side of the meter into the RCBO. The solar guys did all the loft work but had left site before I'd […]
- Hi all, We want to get our house rewired and have been told that wiring in the loft will be left loose sat on top of insulation. Unless we remove the insulation ourselves then the wires can be secured to I assume sides of joists. The old wiring is clipped to the sides of joists […]
