I have a problem with most of the sockets and switches that have been installed in my flat. The original electrician installed the holders (?) flush (see pics) but the replacement guy installed them jutting out from the wall (drywall) a couple of mm. This has led to an ugly gap between the...

Thanks for the replies. Attached is a pic - after asking around a but more, I found out that (as MikeR said) it is indeed a bus bar which allocates circuits to phases on a consecutive basis. I am not happy leaving this as is - firstly as it's my house I want to know what's connected to...

Building a new flat, and the power supply is 3 phase 3X25A. My contractor changed the electrician half-way through the job. The previous electrician was going to wire all the phases together (to my understanding in effect simulating a 75A connection) The new guy is a bit of an #$@%...

I ran some figures on using sleeved anchor bolts, assuming I had 2000 psi concrete to attach to. Having only 20cm available to bolt to the wall edge gave me too big a moment (at least according to my calcs....) - I could have added some struts fixed to the inside lip, but I wasn't too happy...

I am taking on a metal railing for a concrete balcony. The widest edge is 5m long, with no side (wall) supports. (//www.diynot.com/forums/viewtopic.php?t=285380....) Up until now I had planned to drill 200m into the concrete ledge and anchor the posts that way. A friend suggested that I...

Are the screw and nut holes not a point of ingress ? I assumed some moisture would penetrate there...

I am putting together 11m of (outdoor) balcony railing. Spindles are 20mmx5mm strips (hot dip galvanized) connected to rails by 5/32" screws and bolts (galv) Rails are 20mmx20mm square profile bars, 2.5mm thick. Cold galv. connected to Posts by 1/4" nuts and bolts (galv) Posts are...

Correct, the railings are new and untreated. That's why I thought of painting with Hammerite for galvanized directly - is that not possible ? If I go ahead and paint with a red oxide primer first, do I need to do anything besides clean/degrease ? Thanks D.

Hi, I need to paint a balcony railing that's a real mix of metals (all new and unpainted). 1. Cold-galvanised metal profiles 2. Hot- galvanised metal strips (a little bit of chips in the galv layer at edges) - these have some flexibility to move (over a 500 mm length they can bend a...
