You’d be looking for a new job if I saw you running separate earth bonds for each cable. It’s a waste of materials and confusing.

All our panels with small SWA’s like that would have two banjo’s per gland and a single 16mm[SUP]2[/SUP] bond to the EMT. The banjo’s on the outside so there was brass to brass contact.

That looks like it will be much neater, can i ask what determines the size of the bond? you state 16mm2 but is that by calculation or just experience?

This is one of my more recent jobs. She could not stretch to a panel heater so I said I would loosen off the neutral so she could have a consumer unit / heater combo.
OBVIOUSLY, THAT COULD NEVER HAPPEN IN A STEEL CU, COULD IT? :ack2:
 
Not directly an install but made me laugh when I saw this in a mess room.

that's the combustible CU problem solved. fit a tap above the CU with a temperature controlled valve. soon as the temperature reaches 85 deg. C, tap turns on, extinguishes fire. nationwide that'll be 5000 firefighters made redundant, or demoted to getting ----- cats out of trees.

At one time M&Q specified 7/064 /16mm[SUP]2[/SUP] as minimum and I’ve always stuck with that. Our stores would usually have a couple of 100m of it and I’d rather have my fingernails pulled out than try to get them to order anything different. Looks a bit silly when you have a 1.5 2c SWA with a 16mm run to it, but it’s what they wanted
