I'm preparing an electrical drawing to be submitted to my AWJ (Authority with Jurisdiction) which uses NEC 2014 and IRC 2018. (Important because NEC 2018 changed some requirements). My system is 36 panels producing 12.9kW Dc, and 2 Growatt 5000MTLP-US 5kW inverters, with integral Dc disconnects...

Hi All I have around 30 garden lights which turn on and off with one switch in the house. The problem is, if water gets in one light it a) stops all lights working and b) requires troubleshooting 30 lights to find the problem. Therefore, I was planning to have a second distribution board...

Hi. I'm a newbie in this forum. I'm a homeowner who's done plenty of simple lighting, outlets, etc. even including a couple of circuit breakers. I've never done a 3-way switch before though, let alone a 3-way smart switch. I've been doing my homework, but would still like a sanity check. The...

Hi all, Thanks for the help in my previous thread, I got things working well in the end: As to my new question, I have the following one-gang switch in my kitchen/diner which powers an outdoor PIR/LED floodlight: So this has a twin+earth and a 3 core+earth cable - I'm guessing the...

I have just received a wifi switch that does not require a neutral. As far as I thought, it would then be a straight swap with the existing 2 gang switch. However, I can’t seem to see an Earth on this new switch and looking at the current wiring I can’t see how it would switch over. Any ideas? I...

Hi all, Recently my gas stovetop's ignition button started malfunctioning. So of course, I took it apart and found a replacement. So the button seems to have two flat pins that plug into a plastic box with some plate inside. The other end of the plastic box ends with two holes for the cables...

Hi, I have recently noticed that our shower isn't working, and that the socket to power the shower (located just outside of the bathroom) doesn't flick on, it stops halfway - so you can have it 'OFF' or halfway to 'ON'.. it won't fully click and give it power. Pics attached. Anyone have any...

Can l safely remove 2nd set (3 wires) from my temporary power box when l pull down the shut off switch

Hi, I have just replaced an old isolator switch on our shower and have discovered after wiring that the old live wire is a little exposed through the cable shield (presumably where it has been snagged in the ceiling at some point - see photo). I'm a little concerned that this could be a...

Probably an easy answer but I need to clarify. I have a 2 hand switch with 3 wires. All red wires, no neutral. One will be the common which will go into L on the new switch and the other 2 will go into L1 and L3 (that's the only connections with terminals) . Lights are not working so what could...

Ok, so basically I turned the oven off at the wall when we went away for our honeymoon, came back yesterday switched it back on and now have no power at all.

Hi all, I was having some work done as I've moved into a new house in Feb. My electrician did all the wiring for a new partition in the front room but has been detained in the EU because of the 2 week isolation period. I've managed to wire up the outlets but have no clue what's going on with...

I wanted to ask this question to the pros because Google has a bunch of useless answers. We have a lamp in our living room that is a basic twist switch table lamp. When we went to bed I turned the lamp off. My son woke me up around 1:30 am and when I went to his room the light in the living...

Hi there. Quick one for you hopefully. Used an mk grid switch dimmer to switch GU10 led lamps. Load is well within the rating but soon as dimmer is on there's a hum. From both the dimmer and other two way switch and also the mcb. Take it out it all stops. The mk instructions do state to not use...

I have a 2-way wall switch that is on a circuit for a room. The switch does nothing, although it is receiving power and when switched it does correct on/off the power to the second terminal (so the switch is working). I believe this switch is supposed to control an outlet receptical in the...

Afternoon! Below is a picture of my Reliant Outlet and Transfer Switch Box. My inside panel does not have anything telling me about what I can run if I plugged in a generator to this outlet. I understand I have to turn off the main breaker if the power was off but do I turn on the 30A and 20A...

I was hoping to replace old light switches in my house, but am confused by the current switched / wiring. The switch has 2 Common slots, unlike any new switches. There are 2 ceiling lights in the room, but only 1 switch for the lights in the room. On new 1 Gang 1 Way switches there is only 1...

So I've seen some posts in the past about smart switches needing a neutral at the switch. I have a rewire coming up and was planning to use 3 core and earth as the switch line for some switches (2 gang switch will need just 1 neutral from a 3 core earth and the other SL can be T+E) as the switch...

What would you recommend as an 80A DP mains isolator switch? Background: My DNO fitted a 100A cut-out fuse on 16mm2 service cables, despite their own published policy requiring 25mm2 service cables for such a fuse rating. (At least, the fuse carrier is labelled 100A). So, they are coming out...

Hi, Please see the existing dimmer switch wiring with the Live & Neutral wires. In the new dimmer switch, I've tried the Neutral in N only. I've then tried the Live wire (brown) in the L & L1. In L the light remains on all the time despite switching. In L1 the light remains off despite...

Could anybody help with re wiring my 3 gang switch please

For a lighting circuit, Do you consider it bad practice to have joint in neutral at a switch box instead of separate joint box or 3-plate ceiling rose?
