i mean sure, but thats a complete system in of itself right? you would do gabions instead of a wall. I'm just trying to figure out how people backfill in against a wall like this with appropriate gravel. Its a bit easier to figure if i'm digging into the high side of a slope as in that case...

My garden is heavily sloped, and i have embarked on a project to create a flat "terrace" if you will. To achieve this i'm planning to build a 1m high retaining wall along the bottom edge of the garden, then dig out some of the higher area and backfill in against the wall, giving a flat usable...

Yeah that was my worry, and 30mm at the high end near the door means maybe 80mm or more at the lower side, which given the roof pitch will make a real dent on the headroom right where its needed the most. The rear wall of the garage is ~5 feet high, and its a monopitch roof at around 15-20...

My garage floor is extremely uneven. The surface is rough and broken up in places, and also the floor slopes down maybe 50mm or so over the length of the garage. I'd quite like to fix it, and i've heard of self levelling compounds etc, but i've no idea if these are suitable for such an...

The main stacks are vented at the other side of the house, 110mm goes all the way up thru the roof for those. This vent line just seems to be for the branch to the downstairs loo. Cheers

We have a cellar/utility space at the side of the house, which contains some plumbing/electrics and the boiler. In this space is a 40mm waste pipe, which picks up the boiler condensate and the downstairs toilet sink wastes, and feeds them down into a 110mm soil pipe, which picks up the...

Already booked WB fixed price repair this evening and the boiler is indeed turned off! As stated in my first paragraph, thats not why i created the thread! I just dont want a repeat of last time, and frankly i trust these guys no further than i could throw them. The pump debacle was certainly...

Hi Guys. I realise asking boiler questions on here tends to illicit a typical response of "call a guy", but hopefully we can have a sensible discussion with regards to whats going on here. My last encounter with WB engineers was not pleasurable, and as we'll get to later, may even be part of...

AFAIK they are, they just need to be interlocked?

More volts doesnt generally reduce the current on a resistive heater. It will not magically stay at 2.99kw if its rated at 230v and you feed it 240v, it will simply draw more power.

because the supply loops around each light fitting in turn, and you've disconnected the circuit in the middle.

There seems to be panic around the fact that theres a big DC battery... But something like a industrial motor drive inverter runs AC into a big DC Bus running 600+volts, and no-ones jumping about with those incase some of the DC sneaks out into the mains?

The pod point your quoting from is a wall mounted charger designed for permanent installation. They added the DC stuff when the 18th edition came out AFAIK, and clearly yes, these are designed to be installed by a professional electrician who can (should) check these things and ensure its all...

Youtube video time? :P

There should not be a DC current unless there is a fault, and if there is a fault, the charger itself should turn off. Thats the point of putting all the protection into the charge unit. But if you want to swap the RCD, then go for it, assuming its available and cheap enough.

So called "granny chargers" have the RCD protection built into them. They're designed to be jammed into any old 13A socket. So in theory it shouldnt matter that there is an AC RCD on the board.

Having spent a while on some EV forums, i can tell you long term charging on a 13A socket will not end well. They're just not made for continuous high load and will eventually burn out and melt. I would suggest you at the very least go for something like the OHME charger and fit a commando...

There are two photos. The first photo shows the empty terminal block, and clearly shows an earth wire, suggesting the fitting requires earthing. The second photo, which Winston is referring to, shows the light wired up with 2 core cable, and thus no earth connection. The OP asked if this...
