[QUOTE="steptoe, post: 17024, member: 7"] yes, I know exactly what the 50v rule is, and if you bothered reading many of my posts you would know this, 1663ohms is perfectly acceptable if you use a 30mA RCD, which you should be doing to comply with 17th, its the DNO that usually wont accept anything above 200 ohms, nothing to do with the regs whatsoever, unless you can show me where it says so! there is NOWHERE I can think of where a maximum is stated for a TT system, the ONLY way to obtain it is by calculation of the 50v rule and rating of RCD. sorry about questioning the wind up, it just sounded strange to be asking this sort of question while sounding unsure of some fundamentals. ?:| [/QUOTE]
