520 or something.
That's a fairly decent record and beats even screwfix, and that covers loads of trades. I mean DIY topics. Ha

I recently moved into a new house that had a ring camera hard wired using bell wire. This was also hooked up to the houses old chime. I didn't want the ring camera so switched it for Eufy C31 which I also want to hardwire in the same way. Unfortunately the transformer for the Ring only supplied...
Hi
I popped round to quote for ‘ finishing ‘ a solar install started by a company rhyming with Bird of Polar . The house has a three phase supply, but it looks like someone has taken the three live tails into board not designed for three phase (albeit with a three pole switch).
They’ve only...
Morning all,
Little advice regarding whether spuring from a Three phase isolator to a single phase FCU is allowed?
I need to wire a Single phase FCU which is located right next to a 16A TP isolator to a high speed door. Obviously, It would be a lot less pain to wire straight from the TP...
Silly question I'm sure, but I'll ask anyway.
On a 2 way lighting circuit the black and grey conductors get sleeved brown to show they're line conductors and I'd like to know why as black and grey are line conductor colours anyway so surely if the grey isn't sleeved blue it's a line and if the...
I have a scenario where there is a three phase DB in a commercial property where there are mixture of three phase and single phase washing machines.
All the washing machines including those that are single phase have triple pole MCBs installed and wired in 5-core to 16A rotary isolator. from...
I can't seem to find the right answer for a smart switch installation for a light that has THREE switches. There's conflicting information, and most of it is for two-switch installations and not three-switch installations. Do I need to install a three-way smart switch at each location, or can I...
We are excited to bring the news that from September to November this year, PCBWay will participate in three new exhibitions. They are Electronics & Applications 2023, SIANE Industries 2023 and Advanced Engineering 2023.
During each exhibition, PCBWay will showcase a diverse range of samples...
Hi
I have three phase installed recently to increase generation.
DNO approved the extra 2 solar arrays so we have 3.68KW FIT on one phase and 8KW on phase 2 with 6KW on phase 3
We are coming to the end of the install and my question is as the DNO have limited export to zero how do we share the...
Hi there
currently doing some diversity calcs for college work and had a query about what diversity factor to apply to a 16A 3 phase commercial food holding unit.
I'm thinking that this equipment will be only used in the day time(breakfast, Lunch and Tea (what we call the evening meal- dinner...
I've got a security light which has two wires like a normal ceiling lamp (the first wiring diagram attached).
I bought a new security light which has three wires (live, neutral, earth), attched is an image of that.
There is also attached a picture of the current security light with its live...
Hello,
I am currently working with 2 separate circuits, one for the dust extraction and another for a circular saw.
Both circuits have an isolator with 3 phase and neutral then each goes off to its own dol starter.
I was wondering if there is a way to make them both turn on at the same time...
Hi All,
From what I understand, working out the design current - Ib for single phase is quite easy (max appliance power/voltage).
For three phase, do I take the max power, divide by 3 then divide by 230 to get the Ib?
(We definitely use 230V for everything right?)
Now for voltage drop, We...
Hi everyone, this ones a first for me but weve been asked install and use a three phase supply in a large new build house. The 16 way dis board is going to go in a ground floor store / plant room and will give us either 48 single phase ways or a few less if we use some three phase 22kw EV's...
(Thought I'd already poost this Q, but I cant see it, so I'll try again)
We have some work going on in one of our buildings atm. On of the chaps has drilled into a cable that was buried in a wall in a fairly random location, knocking out the power to one of the flats (and giving him a nasty...
Hi ,
Currently doing a design project in college and I need to pick a circuit breaker ( In device rating and type) for a food holding equipment unit that requires a 16A 400V three phase and neutral supply that is supplied by 5 core SWA. I think I should pick a 16A 3P+N RCBO but wasn't completely...
I am an enthusiastic retired engineer rebuilding a barn in France from scratch and am having problems sizing my incoming electrical cables. I have had answers from 4mm to 50mm cross section from various pages on the internet so you can understand I am a bit confused.
There are two main cables...
