I have worked on XRay equipment for industrial use and the indicator warning light was a little lamp with a non standard resistance. Part of the pre start was to measure this to make sure the warning lamp would work before starting. Ofc you had to buy OEM parts at silly prices and lead times...
I'm glad its not just me who cant see the need for this.
The enclosure holds a few PSU's, 3 low power relays , 1x 2.2Kw VSD and some IO's. Nothing that I would say is high risk of going on fire. Its not in the way of any fire exits from memory. I'm going to look at it tomorrow and see what they...
I have not read the fire risk assessment myself yet but i think the concern was a fire starting in this remote MCC. Probably only as flagged as an issue because the rest are out the way and this guy looks a bit out of place because its the only one on the floor.
Well it would only block once it was hot enough for the intumescent strip to expand and seal it off. So far outside if normal operating temperature. Atleast thats what I think they want
Yeah. I am a bit worried about it being blocked up I guess if it was to block there is something else going on. Its no Ex im not interested in that just a cautious light industrial production factory.
Hello, I am looking for advice in the best way to seal a vent on a control cabinet. The MCC is 1000x600x300 wall mount with a standard vent at the side. The customer has asked about this after a fire risk assesment. I have honestly never put any thing like that in before as most MCCs were in...
It doesn't look great from the photos. The lack of CPC on the metal faceplates is the most concerning, as for the cables being twisted this isn't a concern too me. I would ask you contractor if this is his usual standard of work and explain why you are concerned to them. If he can not make the...
only needing to test the ac part is crazy, unless it just to proven the mechanism works? at that point just use the test button and hope it will disconnect the same way we are hoping it will disconnect in a 'type a' fault
Thanks! Thats good to know.
I feel testing is way behind with current tech. The guy from meggar touched on it too, when saying they aim for 5% for earth loop testing but the requirement is to be within 30%. We are worrying about 0.1 ohm and the machines we are getting the values from can way out...
Just watched the full video. Actually pretty good.
One concern I have after watching this is disconnection times. They spoke of capactive loads slowing the disconnection time done.
Now what happens in a real world fault where someone is relying on an RCD for fault protection but there is a...
I never understood why there is a need to time the rcd performance. We are happy to measure the earth fault loop impeance and from that say the mcb will operate correctly. I wonder if any other coutries feel this level of detail is needed.
is this a hangover from back when RCDs were seen the...
maybe not so helpful but I would avoid DETA, I feel the screw terminals were awful and I think it was the FCU that would not fit onto a single backbox unless you bent the top and bottom lug out of the way. This was a while back on a job that spec'd the brand.
Hager sollysta is pretty good, the amount of packaging and these little white covers are a bit of a pain but look good when fitted,
Prices are ok online with most wholesalers stocking them also if you get caught short of stock
Hello, I am looking for a door entry system with fobs to operate a mag lock on a door. Ideally I would have a system which records of log of what fob and when opened the door. What makes would you recommend looking at or avoiding.
Thanks
