Hi All,
I’ve no power to my workshop so a proper qualified electrical contractor is coming to wire it up shortly.
They wanted me to lay the cable from the house dropped of some armoured cable a couple of months ago (16mm) but it’s taken a while to dig the trench as it runs 200 foot through three foot of concrete and hardcore where we park cars but I think I’ve got it down deep enough -600mm but put the cable in a twin wall duct and poured concrete over that with the obligatory cable warning tape over the concrete and a second run embedded into it too. I’ve left the trench open to show them. I’ve drilled through the concrete workshop base with a core drill and eased the cable and up through into the shed so it comes up almost vertical.
Q1 - can anyone advise if this sounds acceptable and what protection do I need round the SWA in the workshop as it heads up from the floor to the metre board?
Ive fitted a 600mm by 300mm meter board on 70mm by 45mm batons to the wall about four feet up.
Q2 - Will this be meter board big enough for the consumer unit?
Q3 - what sort of consumer unit do I get for the electrician or would they bring one - in particular should it have RCD (the other end of the SWA comes out in the junction box outside the house and I understand wil be connected to the mains there).
From the consumer unit I’ve set up conduit with 90degree connectors that goes up, across the roof beam and down the other wall 8ft opposite to an identical meter board where i want to put two double sockets.
Q4 - I’ve only got one run of conduit - will this be enough or is it supposed to go round in a ring.
Q5 - I’ve not bought the sockets yet. Do they need to be robust metal faced or full exterior sockets with covers - for a the inside of a shed. It’s just a regular newish wooden workshop 20ft by 8 ft. Do the sockets need their own rcd switch if the consumer unit for the workshop has one or would two sets of rcd protection be problematic.
I’ve also ran a second conduit to an interior bulkhead light with an exterior switch in between.
I’ve not put wires in anything (other than laid the SWA) as I’ve not a clue what wires are supposed to go in and assume they fit the wires and strip connect up the SWA etc. I’m doing what I think they expect me to do but if it’s all wrong I imagine they will tell me to fix it. I’m asking to mitigate the risk of that as it takes a while to make a booking for them to come out m. I’ve only been able to get the office admin person when I phone so have not been able to ask them all of this.
Sorry lots of questions but I want it to be right for when they arrive but I can’t reach them to ask. They are a big and well known contractor in our town.
